Product Overview
Helium Leak Testing Basics
Helium mass spectrometry, or helium leak testing, is a highly precise means of leak detection.

At the heart of helium leak testing is a complex piece of equipment called a helium mass spectrometer. Quite simply, this machine is used to analyze air samples (which are introduced into the machine via vacuum pumps) and provides a quantitative measurement of the amount of helium present in the sample. In practice, a “leak,” is identified by a rise in the level of helium being analyzed by the machine.
