Helium Mass Spectrometer Leak Detector refers to as a diagram with helium or hydrogen gas leak, a gas analyzer helium mass spectrometer leak. The low noise floor of helium, small molecular weight and viscosity coefficient, and therefore easy to spread easily through the drain hole; In addition, the inert gas helium-based, non-corrosive, it is commonly used as shown helium gas leak. This gas will then have to spray the gas analyzer (adjusted only for helium from the operating state of the reaction) was seized container, if the container tainted holes, namely the analyzer to react, so we can see where the leak and drain volume size.

Smallest Detectable Leak Rate(He)(Pa*m3/s):1.0×10-13Pa·m3/s
