Abstract

Embodiments of the present disclosure provide an ion mobility spectrometer device. The ion mobility spectrometer device includes: an ion mobility tube, a sampling device, and a sampling and circulating gas path. The sampling device includes a solid sample desorption device and a gas sampling device. The solid sample desorption device is configured to process the solid sample into a first mixed gas containing the solid sample, and the gas sampling device is configured to process the gas sample into a second mixed gas containing the gas sample. The sampling and circulating gas path is configured to transfer the first mixed gas and/or the second mixed gas into the ion mobility tube for detection.
