Abstract
The present disclosure discloses a gas chromatograph-ion mobility spectrometry combined equipment, including: a gas chromatograph device for pre-separating a to-be-detected sample to form a pre-separated sample; an ion mobility spectrometry device in fluid communication with an outlet of the gas chromatograph device for detecting the pre-separated sample; and a gas circulating device in fluid communication with a discharged gas interface of the ion mobility spectrometry device for processing a discharged gas from the ion mobility spectrometry device, wherein the gas circulating device is further in gas communication with the gas chromatograph device for conveying a part of the discharged gas to the gas chromatograph device to serve as a carrier gas, which drives the to-be-detected sample to enter the gas chromatograph device. The miniaturization and the portability of the gas chromatograph-ion mobility spectrometry combined equipment are improved.
