Bottle Leak Testing Using Helium - Tracer Gas Method

Bottle Leak Testing Using Helium - Tracer Gas Method

Pharmaceutical bottle integrity testing is an important step in assuring that the product is safe and unadulterated. It analyzes the strength and integrity of the closure mechanism as well as its capacity to maintain a sterile barrier. Container closure integrity testing analyzes the materials and chemicals for the possibility of migration or leaching into the drug product, resulting in contamination. Microorganisms, gases, and other chemicals are examples of contaminants. Container system integrity testing involves evaluating primary packaging, or everything that comes into direct touch with the product, as well as secondary packaging components required for package assembly. Helium leak detection, airborne ultrasound, vacuum decay, and high voltage leak detection are all methods for verifying the safety of container closures.

Helium Leak Detection to Ensure the Integrity of Bottles

Helium leak detection is referred to as a method of finding leaks in a sealed or enclosed system using the helium tracer gas method. The amount of helium that leaks through a breach is measured and is stated as a leak rate. It is an effective container closure integrity test technique for determining the integrity of pharmaceutical and parenteral products. Helium leak testing guarantees the sterility of drug substances and drug products packaged and, therefore, enhances patient safety.

In this method, the package is filled with helium and subjected to vacuum. The quantity of helium that exits the package is measured using a helium leak detector. The result is expressed as the leak rate. Helium leak testing, in addition to being a highly sensitive container closure integrity test technique, is also useful in product design, product quality analyses, failure analysis, and validation.

What are the Applications of Helium Leak Testing?

Some of the most important applications of helium leak testing include:

  • Ensuring container closure integrity.
  • Selecting closure formulation and configuration.
  • Seal integrity monitoring during stability studies.
  • Verification and prediction of shelf-life seal integrity.
  • Useful in the early stages of developing a pharmaceutical product packaging system.

Helium leak detection offered by LDA (a PTI company) is one of the commonly used leak testing methods that can be used for pharmaceutical package leak detection. Bottles can be tested very effectively using this method. The applications of helium leak detection are also found in vials, prefilled syringes, foil pouches, and cold form blister cards. LDA has long-time expertise in designing leak testing equipment for pharmaceuticals and medical devices.
