Abstract

The invention discloses a device for relieving sample introduction capillary pollution through mass spectrometry. The device comprises a sample storage device, a mass spectrometry detector, a four-way control valve, a filter sand core, a purge gas source and a tail gas treatment device; the four-way control valve is at least provided with four connectors; every two connectors form a group; the filter sand core is rotatably mounted in the four-way control valve; the filter sand core is rotatably communicated with any group of connectors; the sample storage device and the mass spectrometry detector are connected to the connectors; the filter sand core purifies a sample entering from the sample storage device; the purge gas source is connected with the connector; and the tail gas treatment device is connected with the connector, and the tail gas treatment device is used for treating waste materials discharged from the filter sand core. A sample to be detected is conveniently filtered and then is detected, a filtering part is conveniently cleaned subsequently, the service life of the filtering part is prolonged; and meanwhile, the device is stable in structure and simple in operation.

Description

Technical field[0001]The present invention relates to the field of mass spectrometry, and more particularly to a device for mass spectrometry to slowly reduce sample capillary contamination.Background technique[0002]Mass spectrometry techniques have the advantages of high sensitivity, strong qualitative ability, good versatility, and gradually become one of the main technologies of rapid analysis of complex samples.[0003]In the premise of ensuring the vacuum of mass spectrometry instruments, ensure that the sample molecules to be tested efficiently enters the key components of the ionization source, usually use capillary (quartz capillary, metal capillary) injection, film online enrichment Several main injection methods of atmospheric pressure injection. The capillary injection mode is simple, and the capillary of the inner diameter is selected according to the ionization zone vacuum, and one end is placed in the instrument ionization zone cavity, and the other end is placed in the ...
