General Description
The Itemiser DX is a desktop system that detects and identifies microscopic trace particles of explosives or narcotics on persons, places or things. The Itemiser DX is used worldwide by government and commercial entities at personnel, vehicular and cargo checkpoints.
Technical Description
Ion Trap Mobility Spectrometry (ITMS). Enhancements to ion mobility spectrometry (IMS) analysis through ITMS technology allow for vast improvements to ionization efficiency, and therefore sensitivity of the detector. ITMS enables extremely low concentrations of electrophilic vapors, such as explosive vapors, to be detected - impossible with traditional IMS.
