The technical principle is as follows: the sample to be measured is ionized in the atmosphere or in a migration gas to form charged particles, and then drifts in an external electric field. Because of the different mobilities of different samples, different components in the sample separate within the migration tube, and heavy molecules generally travel slower than light molecules. Thus, whether the components of the sample contain TNT explosive molecules or not can be known according to the migration time obtained by measurement; one is to detect explosives such as TNT and the like by using an imaging technology and a nuclear technology; the other is based on neutron detection technology; and reacting the molecule to be detected with a specific functional monomer by using a fluorescent molecular imprinting technology to obtain an imprinted polymer for detecting the explosive molecules.
