Introduction of Helium Leak Detector
Helium Leak Detector
Helium leak detector is used to find small leaks or larger leaks in
bigger volumes. The helium is used as a tracer gas and its
concentration is measured. This guide to helium leak testing should
outline the basics of using this leak testing method. Helium is one
of the smallest gas molecules and is inert. Being inert, helium is
relatively safe to use (rather than hydrogen) and will not react
with any of the materials within the part to be tested. In most
helium leak testing applications, a mass spectrometer is used to
detect helium. Although, it is also possible to use a residual gas
analyser. Helium leak testing can generally be between one thousand
and one million times more sensitive than using pressure decay techniques.

Applications of Helium Leak Detector:
1. Pharmaceutical Industry: The pharmaceutical industry has
experienced enormous progress in terms of technological
developments and drug delivery system innovations over the last two
decades. However, such developments have created new quality
assurance challenges for drug manufacturers. As a result,
pharmaceutical manufacturers give major priority to both quality
control procedures and pharmaceutical package leak detection.
2. Medical Devices Industry: In the medical device industry,
package integrity testing is important since product failure
presents considerable risks to patients and healthcare
professionals, as well as liability for manufacturers. As a result,
medical device industries use various CCI test methods including
helium leak detection to ensure package integrity.
