Helium gas does not accumulate in the air, making it easy to ventilate and eliminating the need for specific exposure regulations.Īnother benefit of helium is that it is non-condensable throughout the entire range of technical applications, and lighter than air, meaning that the leak detection process is assisted by the fact that the test gas can escape upwards. It delivers excellent separation of adjacent masses in the mass spectrometer. Technical apparatus cope very well with helium as the detector can separate helium well, rendering it ideally suited to use with technical equipment including leak detectors with mass spectrometers. These are also beneficial to human safety, as it is a relatively harmless substance. Furthermore, helium gas is environmentally friendly: it is non-toxic, non-flammable and non-explosive. Helium is also inert, which means that it does not react with other substances, making it a relatively stable element. Helium is the smallest gas atom, with the exception of hydrogen. There is a low concentration of helium in the air, constituting only approximately 5ppm in atmospheric air, meaning that it has very little background. Helium is an ideal test gas for leak detection for a number of reasons.
