Abstract

The invention discloses gas chromatography (GC)-ion mobility spectroscopy (IMS) combined-use equipment. The equipment includes: a gas chromatography device, which is used for pre-separating a to-be-detected sample to form a pre-separated sample; an ion mobility spectroscopy device, which is in fluid communication with an outlet of the gas chromatography device, and is used for detecting the pre-separated sample; and a circulating gas path module, which is in fluid communication with a discharged-gas interface of the ion mobility spectroscopy device, and is used for processing discharged gas discharged by the ion mobility spectroscopy device. The circulating gas path module is also in gas communication with the gas chromatography device, and is used for delivering partial discharged gas tothe gas chromatography device to use the same as carrying gas to enable the to-be-detected sample to enter the gas chromatography device under the driving action of the carrying gas. According to thegas chromatography-ion mobility spectroscopy combined-use equipment, a miniaturization degree and portability are improved.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a gas chromatography-ion mobility spectrometry combined device. Background technique [0002] Ion mobility spectrometry (IMS) has the advantages of portability, speed, sensitivity and industrialization, and is widely used in military, national defense, industry, environment and clinical diagnosis and other fields. However, due to the interference of other complex matrices such as water vapor in the detection environment, its ability to identify qualitatively and quantitatively is greatly limited. Gas chromatograph (gaschromatograph, GC) is a widely recognized high-efficiency and high-stability separation tool, and it is widely used in the separation and analysis of gas phase substances. In the art known to the inventors, gas chromatography-ion mobility spectrometry devices already exist. The purpose of gas chromatography-ion mobility spectrometry equipment is to ...
