The Science of Helium as a Tracer Gas: Why It Excels in Leak Detection

    In industries such as pharmaceuticals, medical devices, and biologics, helium is widely used to detect even the smallest leaks. In the medical field especially, helium plays an essential role in testing packages like foil pouches, vials, blisters, and bottles. But what makes helium such an exceptional tracer gas? Its tiny atomic size, chemical stability, and high detectability help to find leaks that other methods often miss. In this blog, we’ll explore the science behind helium as a tracer, how it works, and why it has become the gold standard in leak detection. Why Helium Is the Best Tracer Gas? Helium gas is not just for balloons; it is also a powerful tool in science and medical industry for packaging on the purpose of leak testing. Here’s why it’s perfect for leak detection: ·        Helium atoms are tiny, so they can move through the smallest openings. ·        It’s non-toxic, non-flammable, and do...

Critical Factors to Consider when Choosing a Helium Leak Detection System for Cryogenic Storage Applications?

In the pharmaceutical and biotech industries, products such as vaccines, biologics, and cell therapies often require storage at ultra-low temperatures. Cryogenic conditions are essential to maintain the stability, efficacy, and shelf life of these sensitive products. However, extreme cold poses significant challenges to the integrity of packaging. Even the smallest micro-leak in a vial, prefilled syringe, or combination product can compromise sterility, reduce product effectiveness, or lead to regulatory non-compliance.   Helium leak detection has emerged as the gold standard for evaluating container closure integrity (CCI) in cryogenic storage applications. Its ability to detect minute leaks makes it an indispensable tool for manufacturers striving to ensure product safety in ultra-cold conditions.   Container Closure Integrity in Cryogenic Conditions   Cryogenic storage subjects packaging materials to extreme thermal stress. Plastics, glass, and elastomers can shrink,...
