Pulsed sampling-based ion mobility spectrometer and sniffer
There are provided an ion mobility spectrometer and a sniffer. The ion mobility spectrometer includes: an ion migration tube; a sampling gas path having a sampling device configured to temporarily store a sample gas collected by a sampling head in a sampling pipe; a sample introduction gas path having two ends in communication with the gas inlet and outlet of the ion migration tube respectively, and configured to introduce a carrier gas within the ion migration tube into the sampling pipe and to carry a sample gas temporarily stored in the sampling pipe into the ion migration tube; and a valve assembly configured to only allow gas to flow from the sampling device to the sampling pipe in a sampling state, and to only allow gas to flow from the ion migration tube through the sampling pipe back to the ion migration tube in a sample introduction state.
