Abstract

A gas chromatography-ion mobility spectrometry detector and a hyphenated apparatus, the gas chromatography-ion mobility spectrometry detector comprises a gas chromatography mechanism and an ion mobility spectrometry mechanism. The gas chromatography mechanism comprises a chromatographic column and a sample injection port. The ion mobility spectrometry mechanism comprises a mobility tube and a connecting body, while a metal connection plate of the connecting body comprises a chromatographic metal plate, an ion mobility metal plate and a semipermeable membrane; on the ion mobility metal plate there are provided an ion mobility sample and carrier gas inlet, an ion mobility sample chamber and a sample injection port; the chromatography sample chamber and the ion mobility sample chamber are separated by semipermeable membrane.
