The gas control method in the standby state is simple and feasible, and the automatic control can improve the service life of the drying tube in the ion mobility spectrometer.
Description
Technical field
The invention belongs to the analytical technology of chemical analysis field ion mobility spectrometry, specifically the gas control method of a kind of ion mobility spectrometry under holding state.
Background technology
While adopting Ion mobility spectrometry to carry out sample analysis, need to produce continuously clean air by air feed pump, the drying pipe of instrument internal, provide analysis necessary float gas and carrier gas, guarantee the normal analysis state of ion mobility spectrometry.Even under holding state, also to open air feed pump, maintain pure air and carry out purge instrument.
Drier finite capacity in drying tube, in the situation that air feed pump uses continuously, needs the frequent drier of changing, to keep ion mobility spectrometry normally to analyze.The long-time standby if close air feed pump, before again analyzing, need to purge for a long time with pure air, could recover ion mobility spectrometry, enter normal analysis state, so under holding state, maintain ion mobility spectrometry inner clean, reduce the drying tube replacement cycle, just need the gas control method under holding state.
Therefore the present invention, by the gas control method of a kind of ion mobility spectrometry under holding state, addresses the above problem.
Summary of the invention
The purpose of this utility model is to provide the gas control method of a kind of ion mobility spectrometry under holding state.For achieving the above object, adopt the mode of intermittent gas supply, control the time span of air feed, control the ratio of service life and the time of stopping the supple of gas or steam, maintain ion mobility spectrometry at suitable holding state, so that fast quick-recovery enters operating state.
In the mode of intermittent gas supply, control the time span of air feed, time span is 5-120 minute; In intermittent gas supply mode, controlling service life is 1:0.1 to 1:8 with the ratio of the time of stopping the supple of gas or steam.
In the process of intermittent gas supply, the time span of controlling air feed is 15-60 minute, and controlling service life is 1:0.2 to 1:4 with the ratio of the time of stopping the supple of gas or steam.
Gas control method under this holding state, simple possible, controls the life-span that can improve drying tube in ion mobility spectrometry instrument automatically.
