Helium mass spectrometer - Wikipedia
Detection technique. Helium is used as a tracer because it penetrates small leaks rapidly. Helium also has the properties of being non-toxic, chemically inert and present in the atmosphere only in minute quantities (5 ppm).Typically a helium leak detector will be used to measure leaks in the range of 10 −5 to 10 −12 Pa·m 3 ·s −1.. A flow of 10 −5 Pa·m 3 ·s −1 is about 0.006 ml ...

Helium Leak Detectors + Vacuum Leak Detectors
Helium leak detectors also work on principles based from sector field mass spectrometers. Entry gases such as Helium will be analyzed then ionized in vacuum and its ions will be accelerated with the help of added voltage before being separated in a magnetic field. Using a special detector, the helium ion will be turned into an electric current.
