Powdered Dairy Products Package Testing Using VeriPac FLEX Series

Powdered Dairy Products Package Testing Using VeriPac FLEX Series

The sensitivity of a test method is necessary for several reasons, but it is most crucial in ensuring the final product is of high quality. Powdered dairy products (milk powders, infant formula, protein-based powders) are kept in a modified environment to avoid spoilage and maintain the nutritional value of the product throughout its shelf life. Before usage, the product will quickly deteriorate due to oxygen and moisture intrusion, affecting the flavor and texture and finally converting any desirable commodity into a liability. The quantity and impact of oxygen ingress depend on a number of variables, and it will occur in the presence of tiny leaks. Leaks as small as 10 microns will have an immediate impact on the product for smaller packaging types. Current conventional test techniques are completely insufficient for identifying such defects, leaving manufacturing operations exposed to severe quality variations. Applying techniques with greater sensitivity provides the highest level of quality assurance, rather than just locating minor leakage.

Ensuring Dairy Products Package Integrity with VeriPac FLEX Series

For pouches and other flexible packaging, VeriPac FLEX systems are versatile non-destructive package inspection systems. These are available in a variety of configurations for the leak test instrument and the test chamber capacity, with solutions to accommodate small format sachets and stick packs up to bulk size pouches and bags. This is done to accommodate different package specifications and test sensitivity requirements. The Food and Drug Administration (FDA) has recognized the ASTM technique for Vacuum Decay leak testing (F2338) defined in ISO 11607 as a consensus standard for pharmaceutical package testing. This approach is used by VeriPac FLEX Systems.

VeriPac inspection systems are the best alternative for destructive testing since they eliminate the subjectivity of test results and reduce the waste and costs associated with these techniques. Comparing Vacuum Decay leak testing technology to destructive techniques like the water bath or blue dye leak test, it has been found to offer a quick return on investment. The VeriPac test provides reliable critical packaging failure detection and useful packaging process insight.

A Complete Guide to Helium Leak Detection Technology

A Complete Guide to Helium Leak Detection Technology

The quality of the product and the maintenance of the sterile barrier against outside forces are both critically dependent on the packaging. Even a tiny hole in the packaging might allow moisture, reactive gases, or other dangerous elements to enter the product, limiting its ability to heal. Additionally, a contaminated pharmaceutical product can cause serious health issues to the user, making it more of a threat than a treatment. Maintaining Container Closure Integrity is extremely important due to the sensitive nature of pharmaceutical products.

Container Closure Integrity testing is a leak detection technique for determining how well sterile barriers are maintained against external contamination. These tests may be roughly divided into probabilistic and deterministic test methods. Manufacturers choose deterministic test procedures since they provide precise, guaranteed quantitative results. One such test method is helium leak detection technology.

Helium Leak Detection Technology Overview /h2>

Helium leak testing is the method of identifying leaks in various enclosed or sealed systems by utilizing helium as a "tracer" gas and measuring the concentration of the gas as it leaves due result of a leak. A vial is a good example of package system. A pre-filled syringe, a foil pouch, and a cold form blister card are some other examples. Each of these package types is intended to keep the pharmaceutical product contained while preventing the entry of potentially dangerous environmental contaminants like dust, bacteria, or even gases. Helium leak testing method can evaluate these package types. It is a highly efficient approach for finding leaks that provide quantitative leak rate data considerably beyond the capabilities of existing leak testing techniques.

The following describes how helium leak detection works: The package is initially vacuumed and helium-filled. The amount of helium escaping the package is then measured quantitatively and expressed as a leak rate using a helium leak detector. The technique is also ideally suited for packaging line setup and validation, failure analysis, tool qualification, monitoring product quality, and package design.

Why Use Helium as a Tracer Gas?

There are several reasons why helium is considered an ideal test gas for finding leaks.
  • Deterministic seal quality inspection method that produces quantitative outcomes.
  • Regardless of color, transparency, print, surface polish, or porosity, this method works for all material types and combinations.
  • Non-destructive and non-subjective test technique that does not require any sample preparation.
  • Technology may be used for 100% online final pouch seal defect detection.
  • Seal quality inspection results are repeatable, reproducible and reliable.
  • Cost-effective solution for testing seal integrity and seal analysis that characterizes the overall quality and uniformity of the seal.

Helium Leak Detection Merits

  • Practical and sensitive flow-based leak test method.
  • Enables the discovery of extremely small microleaks.
  • Detects leaks with sensitivity levels as low as 1x10-10 mbar L/sec.
  • Helium is a non-explosive, non-toxic and non-destructive tracer gas.
  • Applicable across package design, failure analysis, packaging line setup and validation.
  • Faster test cycle reduces cost and total processing time.

Applications of Helium Leak Detection

  • Vials
  • Pre-filled syringes
  • Blister packs
  • Combination products
  • Bottles
  • Foil pouches

Helium leak detection is the best option for evaluating the inherent integrity of specific primary container closure systems of pharmaceutical and parenteral products. It is a commonly used technology in early stage pharmaceutical package development and component compatibility evaluation. In comparison to other leak test techniques, helium leak testing has the highest level of sensitivity, making it the most used CCI test method.

Package Integrity Testing Systems for Porous Packaging

Package Integrity Testing Systems for Porous Packaging

For packaging sterile devices in the medical industry, porous packaging materials are widely used. The sterile products are frequently packaged, shipped, and distributed to multiple places, where they may be exposed to a range of humidity conditions during the course of the distribution cycle. The leaks in the porous packaging materials can contaminate medical devices as well as products. These leaks are frequently observed at tiny pinholes or breaches in the seals between packing components. Hence, maintaining the microbial barrier of sterile medical devices is of grave importance. In order to maintain the sterility and microbial barrier, various package integrity test solutions can be used. Airborne Ultrasound technology is one such method.

Airborne Ultrasound Technology Overview

Airborne ultrasound is an inspection method for testing seal quality that is able to evaluate seals for defects without causing any damage. It is an FDA recognized standard and ASTM Test Method F3004 for testing seal quality. Such tests are mostly carried out to provide enhanced tray seals, flexible packages, and pouch seal quality inspection. Tyvek®, paper, foil, film, aluminum, plastic, and poly are just a few of the packaging materials that may be used with Airborne Ultrasound technology to ensure in-depth seal quality analyses.

Integrity Testing of Porous Packages using Airborne Ultrasound Technology

Airborne Ultrasound technology is one of the commonly used methods for testing the seal quality of porous packages. In this technique, sound waves are reflected when ultrasound waves pass through the packaging seal. The signal intensity is reduced or destroyed when there is a leak or defect. These variations are meticulously monitored to identify defects. With airborne ultrasound technology, it’s now possible to identify a variety of seal defects, including visible and invisible, leaking and non-leaking, process-related and random both offline in the lab and in automated production environment.

Airborne Ultrasound technology has been proven in the field with both online (Seal-Sensor) and offline (Seal-Scan) solution options. Both of these technologies make use of non-contact airborne ultrasonic testing. It is known to be among the best techniques for non-destructive testing of flexible packaging seals in both offline laboratory testing for seal quality analysis and 100% inline testing on the production line. According to ASTM F3004-13, this is the standard test procedure for the airborne ultrasound evaluation of seal quality and integrity.

Benefits of Seal-Scan and Seal-Sensor Methods

  • Deterministic seal quality inspection method that produces quantitative outcomes.
  • Regardless of color, transparency, print, surface polish, or porosity, this method works for all material types and combinations.
  • Non-destructive and non-subjective test technique that does not require any sample preparation.
  • Technology may be used for 100% online final pouch seal defect detection.
  • Seal quality inspection results are repeatable, reproducible and reliable.
  • Cost-effective solution for testing seal integrity and seal analysis that characterizes the overall quality and uniformity of the seal.

According to studies, the conventional seal inspection techniques are ineffective because they miss undetectable flaws and wrongly reject pouches that are tightly sealed. Airborne Ultrasound is a deterministic seal quality testing method. The technology has established itself as a highly practical solution for non-destructive testing of porous packages. The integrity of porous packages can be tested efficiently using Airborne Ultrasound technology.

All About Airborne Ultrasound Technology

All About Airborne Ultrasound Technology

The integrity of container closure systems can be interpreted as their capacity to maintain a sterile barrier against potential contaminants that could compromise the quality of the end product. The sterile barrier can be damaged by even the smallest leak, which might affect the product's healing properties. Over the years, dye ingress and microbial ingress are common leak testing methods. It has been proven that they provide inaccurate and subjective results. As a result, regulatory organizations have mandated a shift towards more deterministic test procedures that can be controlled, calibrated, and provide a definite determination of CCI. Airborne Ultrasound technology is a deterministic test method mentioned in the revised USP< 1207> Chapter Guidance for seal quality testing.

Explain Airborne Ultrasound Technology

Airborne Ultrasound Technology is a technique for testing the seal quality. It is an ASTM test method F3004 and the Food and Drug Administration (FDA) approved standard for seal quality testing. Such inspections are mainly done to provide improved seal quality inspection of pouches, flexible packages and tray seals. Airborne Ultrasound technology ensures in-depth seal quality analysis and is applicable to multiple packaging materials such as Tyvek, paper, foil, film, aluminum, plastic and poly.

In this technique, sound waves are reflected when ultrasound waves travel through the packaging seal. In the presence of a leak or fault, the signal intensity is diminished or removed. To find the leak, these fluctuations are carefully monitored. More sound is reflected, and less sound is transferred through the seal as the acoustic difference between the medium increases (most evident at the transition from a gas to solid state). The inability to detect non-leak defects is a common challenge faced by most leak test methods. However, users may recognize a variety of seal defects, including visible and invisible, leaky and non-leaking, process-related and random, using airborne ultrasound technology.

Seal-Scan and Seal-Sensor

Under this technique, VeriPac leak testers are connected to a test chamber specially designed to hold the sample package. The package that has been put inside the test chamber is subjected to vacuum. A single or dual vacuum transducer technology is used to monitor the vacuum level as well as how the vacuum changes during a predefined test period. The existence of leaks and other defects within the package is determined by monitoring variations in an absolute and differential Seal-Scan® and Seal-Sensor™ are the two configurations of Airborne Ultrasound technology. Seal-Scan® technology inspects and analyzes pouch seals non-destructively offline. This deterministic, quantitative, high resolution method inspects pouch seals for defects and seal integrity for consistency. Testing does not involve sample preparation, and is non-invasive as well. The technique includes advanced digital imaging software tools for process control that allow in-depth seal quality analysis. Utilizing Airborne Ultrasound technology, Seal-Scan® systems evaluate seal quality and integrity in accordance with ASTM Test Method F3004-13. Seal-Scan® is a semi-automatic inspection system with an x-y drive for the detection of seal defects, seal characterization, and material analysis.

Seal-Sensor™ is an Airborne Ultrasonic technology that inspects the final pouch seal 100% online in a non-destructive manner. Seal-Sensor™ is a deterministic, quantitative, fast, and reliable way to test for defects in pouch seals. The Seal-Sensor™ technology detects defective seals, seals with partial or weak areas, and several other typical seal defects that may not be physically visible but have an impact on the quality, and life span of the product. A pass/fail result and quantitative, traceable data are generated by a single linear scan (L-Scan) of the pouch seal in less than one second.

Why Use Airborne Ultrasound Technology?

  • Deterministic inspection technique yielding quantifiable results.
  • Non-destructive, non-subjective, and does not need sample preparation.
  • Independent of color, transparency, print, surface polish, or porosity, it is applicable to all materials and combinations.
  • Can be integrated completely online to identify defects in the final pouch seal.
  • Consistent and dependable results.
  • Referenced in USP Chapter 1207.Inexpensive method for evaluating the seal integrity of the final pouch seal.

Integrity Testing of Vials with MicroCurrent HVLD Technology

Integrity Testing of Vials with MicroCurrent HVLD Technology

Several leak detection methods, that are deterministic and non-destructive, are already available in the market. Pharmaceutical companies are urged to use technologies that significantly enhances quality assurance and leak detection rates. Appropriate leak detection technology is selected based on the specific characteristics of the product and container, such as conductivity, headspace parameters, contents, or API. Historically, dye immersion and microbial immersion have been the two main methods of vial integrity testing. Recently, the USP has issued guidelines that require critical methods to achieve more reproducible and predictable outcomes. USP <1207> encourages a move towards more deterministic methods, recommending the avoidance of dye immersion tests and the use of quantitative, non-destructive technologies instead.

Why High Voltage Leak Detection Method is Preferred for Testing Vials?

High Voltage Leak Detection or HVLD is a deterministic, non-destructive leak detection method to evaluate vials, cartridges, and other liquid-filled parenteral products for Container Closure Integrity. The current generation of PTI’s MicroCurrent HVLD may be utilized with a wide range of liquid-based products, from low conductivity sterile water for injection to highly proteinaceous drug preparations in suspensions. It is one of the most effective online container closure testing methods, requiring just minor infrastructure modifications. When compared to conventional HVLD solutions, MicroCurrent HVLD utilizes approximately 50% less voltage and exposes the product and environment to less than 5% of the voltage. This method is non-invasive and requires no sample preparation. Like vial leak testing, another major application of MicroCurrent HVLD is pre-filled syringe testing.

Working Principle of MicroCurrent HVLD Technology

In this method, the container is scanned using a set of high voltage electrode probes. A high voltage is applied to one side of the container, while a ground probe is attached to the other. If there is no leak in the package, the two container walls (high voltage side and ground side) offer complete electrical resistance, and no substantial current is measured flowing through the vial. If a micro-leak or fracture occurs in one of the container walls, the break-down resistance is achieved, and the current flows through. HVLD is the only leak detection method that does not require mass to travel through a defect location, instead of requiring just electricity to pass through a crack. Because of this feature, HVLD is sensitive to leaks that conventional leak detection technologies are unable to detect.

MicroCurrent HVLD Technology Advantages

  • Deterministic and non-destructive test method.
  • High level of repeatability and accuracy.
  • Ensure more accuracy and dependability in results.
  • At high production rates, both offline and 100% online inspections are performed.
  • Simplifies the inspection and validation procedure.
  • Highly effective in all parenteral preparations, even liquids with extremely low conductivity (WFI).
  • Outlined in the USP 1207 Guideline.

Pharmaceutical containers like vials protect the product from contamination (sterile barrier) and prevent changes in product quality caused by external factors. In order to determine the functionality of such systems, container closure integrity testing is performed. CCIT provides sophisticated analytical methods for evaluating pharmaceutical containers.

Understanding CCIT's Seal-Scan Technology

Understanding CCIT's Seal-Scan Technology

Package integrity leak test methods offered by CCIT such as Seal-Scan utilize non-contact Airborne Ultrasonic technology for seal integrity testing and seal quality analysis of pouches and flexible packaging. The method is applicable to pharmaceutical as well as medical device packaging.

Seal Quality Testing and Seal Analysis using Seal-Scan Technology

Seal-Scan® is a non-destructive offline inspection and analysis technique for pouch seals using Airborne Ultrasonic technology (ABUS). Seal-Scan® offers advanced digital imaging software tools for process control, including in-depth seal quality inspection. Seal-Scan system uses the non-destructive ASTM Test Method F3004-13 for "Evaluation of Seal Quality and Integrity Using Airborne Ultrasound Technology." This test method was approved using PTI's ABUS technology. Seal-Scan® is a deterministic, quantitative, high-resolution technology for inspecting pouch seals for defects and ensuring seal integrity.

Seal-Scan has two scanning modes:

  • Linear Scan (L-Scan) to simulate online defect identification (line graph)
  • C-Scan for detailed seal analysis, resulting in pixel-by-pixel seal evaluation (Opto-Acoustic image)

Technology Overview

The pouch seal or packaging material is scanned between two focused ultrasonic sensors. Ultrasonic waves travel through single or several layers of bonded materials. The reflection of sound waves caused by ultrasonic transmission via different materials reduces/eliminates signal intensity. The signal level that passes through the seal is a function of the seal's quality. Defects of various forms, such as leaking and non-leaking, process-related and random, can be detected. Seal-Scan® can provide Opto-Acoustic images as well as thorough statistical analysis using one of two scan modes (L-Scan and C-Scan).

An L-Scan is a single linear scan along the seal's X-axis that generates a line graph of seal integrity and replicates real-time inspection. C-Scan generates a series of scans (along the X and Y-axis of the seal region), that offers a high-resolution ultrasonic image of the seal structure. This technology, via the Seal-Sensor, can be integrated into a pouch production process for 100% online seal defect detection.

Benefits of Seal-Scan Technology

  • Deterministic inspection approach yielding quantitative results.
  • Works with any material and combination, independent of color, transparency, print, surface polish, or porosity.
  • Produces a high-resolution Opto-Acoustic seal image.
  • Characterizes the overall quality and consistency of the seal.

Seal-Scan® is a semi-automatic inspection system with an x-y drive that is used to identify seal defects, characterize seals, and analyze materials. This approach is non-invasive, non-destructive, and does not need any sample preparation. The ability of PTI to adapt this technology to diverse production restrictions and conditions makes it an effective solution for flexible packaging systems.

A Quick Rundown on Package Inspection Guidelines for Sterile Medical Products

A Quick Rundown on Package Inspection Guidelines for Sterile Medical Products

Class III medical devices have a unique combination of criteria and package features that necessitate a comprehensive approach to determining the best inspection procedures. For medical package inspection, there are a variety of methods that require a thorough understanding to assure quality.

Manual visual inspection has been the most common form of inspection for medical device packaging. While an ASTM standard (ASTM F1886) covers this concept, it may not be applicable for all applications and has limitations. Even though a 75-micron channel defect can be detected by manual visual inspection, the ASTM method F1886 indicates that the chance of detection ranges from 60% to 100%. This vast range of uncertainty does not give the level of assurance required for the packaging of high-risk medical devices.

Although certain offline leak detection techniques can offer a quantitative evaluation of seal quality, they miss some of the most prevalent seal problems seen in Class III medical device packaging. Testing peel strength or utilizing other destructive methods will not reveal random seal problems. For class III medical devices, online non-destructive inspection procedures are excellent since they provide quality control with comprehensive manufacturing lot data.

All Class III medical devices must be sterile, however, container materials and design differ widely. A non-porous pouch or tray demands an entirely different technique than a porous pouch or tray. Tyvek® offers a sterile barrier, and the porosity of the material limits the leak test procedures that may be used on the package body. When it comes to porous packaging, the focus of online inspection moves away from leak detection and toward seal quality evaluation.

Technology Overview

Vacuum decay and Airborne ultrasound are the two main methods used by PTI/CCIT to inspect medical device packaging. Both methods are aimed at providing quantitative and deterministic test results in order to assess package quality. In terms of function and performance, the two technologies are entirely different. Package integrity and leak path detection are the main objectives of Vacuum decay. Meanwhile, Airborne ultrasound technology focuses on package seal inspection and seal quality. Both approaches aim to meet the basic requirements of being reliable and sensitive inspection procedures for Class III medical device applications.

Vacuum Decay (ASTM F2338)

Vacuum decay is the most practical and sensitive vacuum-based leak test method of CCI. When testing pouches, a versatile adjustable test chamber may be utilized to test pouches of various sizes. The package is then placed into the vacuum-sealed test chamber. The level of vacuum, as well as the change in vacuum during a pre-defined test duration, are both monitored during the short test cycle. The change in vacuum indicates the existence of leaks and defects within the package. Vacuum decay leak testing is a go-to standard for sterile products because of its sensitivity and dependability. The approach is ideal for laboratory offline testing and production applications for quality assurance process control, since test equipment may be developed for manual or automation operation.

The ASTM Vacuum decay leak test technique (F2338), which has been accepted by the FDA as a consensus standard for package integrity testing, was developed using PTI VeriPac technology. As a deterministic test technique for package integrity test solutions, Vacuum decay is mentioned in ISO 11607 and the new USP 1207 guideline document.

Airborne Ultrasound (ASTM F3004)

Airborne Ultrasound is an ASTM Test Method F3004-13 and is one of the most effective methods for non-destructive seal quality inspection of flexible packaging. It is mentioned in ISO 11607 and the new USP 1207 guidance document. Most inspection methods are challenged by the leaking nature of porous packaging, but Airborne ultrasound, with its non-destructive measure of seal quality, effectively overcomes those challenges.

The non-contact Airborne ultrasonic testing technique is used in both Seal-Scan (Offline) and Seal-Sensor (Online). Ultrasonic waves propagate through the material as a package seal passes through the sensor head, producing sound waves to be reflected. When defects are encountered, the signal intensity is reduced or eliminated. The larger the acoustic gap between mediums, the more sound is reflected and less sound is transferred through the seal.

The variety of package forms and materials makes inspecting the integrity of class III medical device packaging a challenge. CCIT's scientists and engineers have vast industry experience and can prove a complete solution, including test method development and equipment validation for Class III medical device packaging.

Package and Seal Integrity Testing Techniques for Nutritional Packaging Inspection

Package and Seal Integrity Testing Techniques for Nutritional Packaging Inspection

Testing the integrity of package seals helps ensure that nutritional packaging provides required product protection. Maintaining the reliability of package seals is critical for product quality and food safety. Airborne Ultrasound and Vacuum Decay technology can be used for testing package and seal integrity of nutritional packages. These CCI technologies produce quantitative, and repeatable results, due to their deterministic nature. The primary purpose of implementing these testing methods is to ensure the safety of consumers.

Overview of Nutritional Packaging Inspection

Nutritional packaging plays a significant role in securely delivering the product. The majority of nutritional products are shelf-stable in nature, therefore package performance is typically a concern. Chemical reactions occur naturally in all nutritional products. Any break in the nutritional packing might lead to the products deteriorating due to air, moisture, and microbial exposure. Fats and other nutrients for infants might become rancid and inactive. The quality and safety of the contents that reach the customer are determined by nutritional packaging.

Package and seal integrity techniques have great expertise in the packaging industry, which helps in inspecting nutritional packages in the most efficient method in order to preserve package and product quality. For the food and nutritional packaging industries, CCIT provides a variety of technologies and solutions. The two most common nutritional package inspection technologies are vacuum decay and airborne ultrasound. While vacuum decay is utilized for applications such as filled and sealed rigid containers, dry products in pouches, and flexible packaging. Retort pouch final seal inspection can be achieved using non-destructive with airborne ultrasound technology.

Technologies to Assure Package and Seal Integrity

Vacuum Decay Technology

Vacuum decay is a package test method for vacuum-based leak detection. It is considered one of the most practical and sensitive test methods used in nutritional package inspection. When compared to destructive test procedures, this technology not only provides for a better understanding of package quality but also minimizes waste. As a result of the waste reduction, the return on investment is higher, and the operation is closer to green initiatives.

The Vacuum Decay leak testing method operates by enclosing package samples in an evacuation test chamber with an external vacuum source. The test chamber is monitored for both the level of vacuum and the change in vacuum during a pre-defined test duration using single or dual vacuum transducer technology. The existence of leaks and defects within the package is indicated by variations in an absolute and differential vacuum. Test systems can be designed to be operated manually or fully automated.

Airborne Ultrasound Technology

Pouches are the common form of packaging for most nutritional products. Hence, it is necessary to ensure the package integrity of such pouches. Airborne Ultrasound is a non-destructive and non-invasive method of inspecting seal quality. In this method, ultrasound waves are permitted to pass through the package seal, causing sound waves to be reflected. The fluctuation in the reflected signal intensity is used to detect defects.

Airborne Ultrasound technology is available in both online and offline solution options. It has been proven to be one of the most successful non-destructive testing procedures for flexible package seals. According to ASTM F3004-13, this is the standard test technique for evaluating seal quality and integrity using airborne ultrasound. This method has high applicability in the food and nutrition industry.

Vacuum Decay technology and Airborne Ultrasound technology are both ASTM test methods and also FDA consensus standards for package integrity and seal quality inspection of nutritional products. An appropriate testing method for inspecting nutritional packages is selected based on the nature of the product and its package.

Assuring CCI in Parenteral Products

Assuring CCI in Parenteral Products

Container closure integrity (CCI) testing requirements and regulatory guidelines have been rising steadily in the pharmaceutical industry in recent years. Parenteral products are often packaged in a variety of ways. The most common packaging formats are - vials, ampoules, syringes, BFS, and autoinjectors.

Microbial contamination, exposure to gases, water vapor, and solvent loss can all cause product degradation if the packaging is breached. As a result, container closure integrity is an important part of the sterile medicine product's lifespan. Patients may be at risk if the container closure integrity is compromised. Drugs that are meant to save lives might lose their effectiveness or cause catastrophic adverse effects. CCI defects might cause oxidation, hydrolysis, or a loss of vacuum, which would have a major influence on the drug's efficacy and shelf life.

MicroCurrent HVLD to assure CCI in parenteral products

The criteria and purpose of the test determine the optimal container closure integrity testing technique. The sensitivity and reliability of the test method, the material of the basic package, and the necessity for inline vs. offline testing are all considerations to consider when choosing the right CCI test method. CCI test procedures such as MicoCurrent HVLD can detect breaches before they become an issue with the product and ensure patient safety.

MicroCurrent HVLD is a non-destructive, highly sensitive technology for parenteral product leak testing. This test technique detects pinholes, microcracks, stopper/plunger leaks, non-visible leaks under crimping, and a variety of other defects by scanning a non-conductive container sealed with electrode probes. A change in current flow indicates the presence of a leak, along with the approximate location of the defect in the container. This is a patent-pending high voltage leak detection technique that has been found to be extremely effective in a variety of applications, including pre-filled syringes, vials, cartridges, ampoules, BFS, bottles, and pouches. Being one of the most effective online CCI testing methods, MicroCurrent HVLD requires very minor infrastructure modifications. This method is non-invasive and does not need sample preparation. It is one of the most effective CCI methods.

What sets MicroCurrent HVLD apart from traditional HVLD technology?

MicroCurrent HVLD, as referenced in USP 1207, is a unique High Voltage Leak Detection Technology for container closure integrity testing. When compared to traditional HVLD solutions, this method uses around 50% less voltage and exposes the product and environment to less than 5% of the voltage. MicroCurrent HVLD is a non-invasive CCI technique that does not require sample preparation, and has a high degree of reproducibility and accuracy throughout. This ground-breaking technique can be applied to a wide range of liquid-filled products including low conductivity sterile water for injection (WFI) and highly proteinaceous pharmaceutical products within suspensions.

Any breach in the sterile packaging systems can cause environmental pollutants to grow, turning a life-saving medicine into a potentially fatal microbial soup. This technology is highly effective across all parenteral and biologic products. At high production speeds, the MicroCurrent HVLD technique is scalable and can easily migrate from offline to 100% inline testing applications. It is a cost-effective online container closure testing solution.

The rapidly increasing preference towards parenteral products continues to fuel innovation, but it also faces distinct challenges in terms of implementing a container closure integrity testing strategy. Parenteral product packaging can be as complicated as the products themselves. To ensure package integrity, CCI testing in accordance with current USP 1207 guidance and regulation is required.

Evaluating Package Integrity Solutions for Vials

Evaluating Package Integrity Solutions for Vials

Sterile pharmaceutical products including vials are manufactured with extreme accuracy and zero tolerance for error. As a result, pharmaceutical manufacturers place a high value on their quality control procedures. This is to guarantee that the items meet the quality requirements for their intended application. Packaging is essential for maintaining product quality and providing protection from harmful external forces. Package integrity testing, in addition to selecting suitable packing material, is a crucial component in preserving product quality. It prevents external contamination that can have a negative influence on drug quality by ensuring that there are no leaks within the package.

An effective package integrity solution for vials will ensure:

  • The vial is well-protected from external factors that might affect its quality, such as light, oxygen, moisture, and temperature
  • It is safe from contamination

Various Container closure integrity testing (CCIT) technologies are available today. Helium leak detection is one of the leading methods used for testing the container closure integrity of vials.

Helium Leak Detection Technology for CCI testing of Vials

The process of detecting leaks in various enclosed or sealed systems by utilizing helium as a tracer gas and measuring its concentration as it leaves due to leakage is termed Helium leak testing. Simply say, a vial that consists of a container and an elastomeric closure is a good example for package system. The vial is filled with helium and evacuated. The quantity of helium that escapes from the package is quantified and expressed as a leak rate. A prefilled syringe, a foil pouch, or a cold form blister card are another example. Each of these package types is meant to keep the pharmaceutical product enclosed while keeping out potentially harmful environmental pollutants like germs, or even gases.

Helium gas has a number of qualities that make it the best choice for package leak testing

  • As helium gas is one of the smallest molecules, it may reliably and rapidly breach pathways.
  • It is an inert gas that won't react with the components being tested, therefore it's perfectly safe to use.
  • Because of its limited presence in the atmosphere (less than 5ppm), instrument noise from atmospheric helium is intrinsically minimal, resulting in very precise findings.

Following are the advantages of using helium leak detection technology for CCI testing

  • Highly sensitive leak test method for CCI
  • Specially designed for detecting extremely small leaks that other leak test methods failed to detect.
  • The leak test thresholds might be adjusted as low as 1 x 10 -10 cc/s using a high vacuum technique. This allows unique comparison amongst package components.

Sterility of vials is essential for reducing and preventing infection in patients when using the medicine. As a result, package integrity testing is essential for regulatory approval of sterile pharmaceutical products, and medical devices. When it comes to package integrity testing of vials, the terms packaging integrity and container-closure integrity are sometimes used interchangeably.

At CCIT, we provide a wide range of quality leak testing equipment for pharmaceuticals including vials. With our high-grade non-destructive testing equipment, you can ensure that your products meet stringent quality requirements.

Evaluating Pharmaceutical Package Sterility with Vacuum Decay Technology

Evaluating Pharmaceutical Package Sterility with Vacuum Decay Technology

The ability to resist microbiological ingress and the entrance or escape of substances is necessary for the packaging of sterile pharmaceutical products to maintain their quality. Pharmaceutical package integrity standards are quite strict since any packaging defect might have a direct influence on the health and safety of patients. USP 1207 explains how to ensure the integrity of non-porous containers used to transport sterile pharmaceuticals. Syringes, cartridges, flexible bags or pouches, plastic or glass ampules, capped vials or bottles, and containers for drug/device combination products are examples of pharmaceutical packaging.

How to ensure pharmaceutical package sterility with Vacuum Decay Technology?

The most feasible and sensitive Container Closure Integrity test method has been proven to be vacuum decay. The test measurement yields a quantitative result that is both dependable and accurate, as well as a pass/fail determination. Vacuum Decay technique works by enclosing sample packages in a tight-fitting evacuation test chamber with an external vacuum source. The test chamber is monitored for both the level of vacuum and the change in vacuum during a set test duration using single or dual vacuum transducer technology. The existence of leaks and defects within the package is indicated by variations in absolute and differential vacuum.

As it is a non-destructive test method, it saves money by not wasting product during leak tests and produces a return on investment in under 6 months for most of the products. Vacuum Decay has shown to be a non-destructive alternative to the blue dye leak test. Vacuum Decay is an ASTM Test Method F2338, which is also recognized by the FDA as a Consensus Standard for Package Integrity Testing. It is referenced as a deterministic test method for container closure integrity testing in the new USP 1207 Chapter Guidance.

Advantages of Vacuum Decay Technology

  • Non-destructive, non-subjective, no sample preparation
  • Pass/fail results backed by quantitative test data
  • Cost effective with rapid return on investment
  • Deterministic, quantitative test method
  • Identifies which cavity is defective
  • ASTM test method and FDA standard
  • Repeatable, rapid and reliable testing

Package integrity must be evaluated as part of a sterility program in order to determine the risk of new leaks occurring during pharmaceutical storage. After understanding the mechanism and the rationale for guaranteeing no contamination, it is recommended that test techniques with detection ability as near as feasible to the maximum permitted leakage limit be utilized.

A Guide to MicroCurrent HVLD Technology

A Guide to MicroCurrent HVLD Technology

High Voltage Leak Detection (HVLD) of pre-filled syringes, vials, cartridges, ampoules, BFS, bottles and liquid filled pouches detects pinholes, micro-cracks, stopper/plunger leaks, non-visible leaks under crimping and many other defects. The HVLD testing procedure also guarantees the security of the product seal by finding tiny pinholes, micro fractures and screen defects that are not visible. Eventual packing defects lead to resistance differential and changes of current flow in the container and the approximate position of the fault. It is also one of the most affordable methods for testing container closure that requires little adjustments to the infrastructure. This technology is not invasive and does not require preparation of the sample. It is one of the most powerful CCI technologies for all biological and parenteral goods

E-Scan HVLD has a high-speed test cycle, produces highly reproducible results and is easy to handle. Fast changeover and easy adjustments of test parameters for various goods and applications are further advantages. Another advantage of the HVLD technique is that it can readily be moved from the laboratory offline to 100% online testing applications at high production speeds. That is an enormous benefit and makes the inspection and validation procedure globally simpler. E-Scan employs a number of electrode probes to scan a sealed container which is not conductive. Glass, plastic or poly laminate might be the container material.

Working principle of MicroCurrent HVLD technology

In non conductive or semi-conductive packing materials, HVLD works by implementing high voltage potential for electrically conductive goods. When electrical discharges between goods and device electrodes are observed, the pinholes are determined. The two container walls (high voltage side and ground side) offer complete electric resistance when the package is not leaked, and no significant current is detected by flash. If one of the container walls has a microleak or fracture, the barrier to breakup is met and the current passes. HVLD is the only technique for leak detection that requires a crack site without mass, needing just the flow of electricity via a crack. This feature sensitises HVLD to leaks that are not identified by typical leak test systems.

Applications of MicroCurrent HVLD

  • Pre-filled syringes
  • Vials
  • Cartridges
  • Ampoules
  • BFS
  • Bottles
  • Pouches

Advantages of MicroCurrent HVLD

  • High level of repeatability and precision
  • Deterministic, non-destructive, non-invasive
  • Product and environmental low voltage exposure
  • Offline and 100% online testing at high production speeds
  • Simpler inspection and validation procedure
  • Most powerful CCI technology for all parenteral and biologic products
  • Robust method and approximate 3x Signal-Noise-Ratio for a wide range of product classes and package formats
