NavigationLatest NewsEX-BEAMS Ltd. is pleased to provide a technical update on its HI-IMS (high throughput ion mobility spectrometry) detection capability. Recently, EX-Beams conducted a series of sensing trials, using our existing detection device, against a range of high value target materials. |
TechnologyIon mobility spectrometry is one of the most widely used techniques for trace detection of explosives and other illicit material. The purpose of an IMS device is to analyze air and rapidly detect explosives or other items of interest that may be present in the form of vapour or airborne particulates. Existing IMS technology analyzes air which is drawn into an ionization chamber where electrons interact with the incoming air molecules to form positive or negative ions. The IMS device measures the difference in the speed of ionic motion (in an applied external electric field), determines the ion type and subsequently identifies it.
