Explosive threat detection

Various Ionization Methods for Trace Explosive Threat Detection by IMS Several articles and books review IMS for trace explosives detection [18, 45, 48]. In particular, a review article, describes many of the product ion formation reactions that create IMS product ions from explosive compounds [45]. The review also contains extensive tables of reduced mobility (Ko) values, which are used to identify ions in IMS, for the most common explosive compounds. 

Differential Mobility-MS for Explosive Threat Detection Differential mobility spectrometry (DMS), also known as FAIMS, is a technique closely related to IMS [191-192]. In this system, the ratio of the electric field strength (E, V/cm) applied to the electrodes to the drift gas number density (N, cm" ) is increased to a level beyond that used in DT-IMS (the most common configuration of IMS systems) so that the mobility of the ion (K) is no longer constant but is dependent on the strength of E/N (Townsend [Td]) [192].
