Routine Leak Detection and Reverse Diffusion Leak Detection

There are two methods of leak detection in helium mass spectrometer, one is traditional leak detection, the other is reverse diffusion leak detection. The basic principle of inverse diffusion is revealed in the determine. vacuum oven is to join the analyzed piece to one conclude of the outlet of the molecular pump, and the leaked helium enters the mass spectrometer tube mounted in the air inlet finish of the pump from the outlet of the molecular pump in opposition to the exhaust course of the pump and is detected.

Battery R&D Equipment is based mostly on the diverse compression ratio (the ratio of the pressure at the outlet of the molecular pump to the pressure at the inlet) of the molecular pump for different mass of fuel, that is to say, it is designed with different levels of reverse diffusi
