Abstract: Provided are an odor sniffing device (11) and a vehicle-mounted security inspection apparatus for a container (1). The odor sniffing device (11) includes a primary sampling front end (116), which has a vent adapter (116-1) having a shape matching with a vent of the ventilator of the container, so that when the primary sampling front end (116) fits with the ventilator, the vent adapter (116-1) and the vent generally cooperate to achieve fluid communication. The vehicle-mounted security inspection apparatus (1) may perform imaging inspection and chemical inspection simultaneously.

Abstract: A trace detection device including: an ion mobility tube ; a sampling gas path module ; a sample injection gas path module configured to introduce a sample carrier gas containing a sample collected by the sampling gas path module toward the ion mobility tube; and a gas chromatography apparatus capable of pre-separating the sample carrier gas, so as to form a pre-separated sample carrier gas; wherein the sample injection gas path module is further configured to be capable of switching between a first mode and a second mode, in the first mode, the sample injection gas path module introduces the sample carrier gas into the ion mobility tube; and in the second mode, the sample injection gas path module introduces the sample carrier gas into the gas chromatography apparatus to pre-separate the sample carrier gas, and the pre-separated sample carrier gas is introduced into the ion mobility tube.

Abstract: The present disclosure provides a gas analysis device and a method for detecting sample gas. The gas analysis device includes: an ion mobility spectrometer including an ion mobility tube, an ion gate, a plurality of electrodes, a suppression grid, and a Faraday plate sequentially disposed in the ion mobility tube, wherein the Faraday plate is configured to receive sample ions discharged from the suppression grid, and the Faraday plate is provided with a through hole; a mass spectrometer; a gate valve disposed between the Faraday plate and an ion inlet of the mass spectrometer; and a controller configured to control an opening or closing of the gate valve to allow the sample ions discharged from the suppression grid to flow into the mass spectrometer through the through hole of the Faraday plate when the gate valve is opened.
