The present disclosure provides a gate system for sample detection and a method of sample inspection, which relate to the field of detection and analysis technology. The gate system comprises: an accommodating apparatus configured to accommodate an inserted ticket to be detected; a wipe sampling apparatus including a wipe sampling belt which is configured to drive the ticket to be detected to move within the accommodating apparatus and to conduct a wipe sampling to the ticket; an inspiratory sampling apparatus configured to collect samples dropped from the wipe sampling apparatus; and a detection apparatus configured to detect the samples and output detection results. The gate system for sample detection and the method of sample inspection provided by the present disclosure have a wide range of applications and can perform rapid sampling and detection to those substances that are difficult to be volatilized.

A minimum-ignition-energy testing apparatus includes a combustion tube and a bottom assembly coupled to a lower end of the combustion tube. A top assembly is coupled to an upper end of the combustion tube. The top assembly includes a first sparge plate coupled to the top base plate. The first sparge plate has a first aperture formed therein. The top assembly also includes a second sparge plate coupled to the first sparge plate. The second sparge plate has formed therein a second aperture that aligns in registry with the first aperture. A channel is formed in the second sparge plate about a perimeter of the third aperture. The channel has a plurality of holes disposed therein that are formed through a thickness of the second sparge plate. A tube is formed through in the second sparge plate, the tube fluidly coupling the channel to a gas source.
