Gas chromatography ion mobility spectrometry detector and gas chromatograph ion mobility spectrometer

摘要

A gas chromatographic ion mobility spectrometry detector and coupled device, wherein the gas chromatography ion mobility spectrometry detector comprises a gas chromatography mechanism and an ion mobility spectrometry mechanism. The gas chromatographic mechanism comprises a chromatography column (112) and a sample injection port (114). The ion mobility spectrometry mechanism includes a mobility tube (111) and a connector body, while a metal connection plate (110) of the connector body comprises a chromatography metal plate (137), an ion mobility metal plate (138), and a semipermeable membrane (139); wherein an ion mobility sample and carrier gas inlet (146), an ion mobility sample chamber (143) and a sample inlet (147) are provided on the ion mobility metal plate (138), the chromatography sample chamber (142) and the ion mobility sample chamber (143) separated by a semipermeable membrane (139) are.
