Introduction: Helium mass spectrometer leak detection method is based on the principle of mass spectrometry analysis to explore the gas was helium , a variety of containers to be sealed quickly locate the leakage gap and quantitative detection of the ideal approach. Because helium is inert gases, atmospheric pollution, the use of safety ; helium atomic weight is small, low viscosity , easy to penetrate any possible leak rate , high sensitivity , high speed , wide application ; coupled with low content of helium in the atmosphere ( only five ten thousandths ) , ion mass ion mass with other gases vary greatly , less susceptible to interference , no miscarriage of justice . With many of today's leak detection methods ( such as bubble method , halogen leak detection method, etc. ) than it is the leader. Technical parameters minimum detectable leak rate :better than 2 * 10-11Pa.m3/s: Commonly used time: About 1H Reaction time: no more than 3S Mass spectrometry allows the maximum pressure of work: 1 * 10-2Pa Leak detection interface: KF25 The outline dimension of the instrument: mm3 950*600*570 Weight: about 70Kg
