T-REX: A Portable Device to Detect and Identify Explosives Vapors

A portable device is reported to detect and identify in real time explosive vapors usually used by the terrorists. This device is composed of the multi-sensors chamber with three technologies of explosive vapors sensors: Quartz Crystal Microbalance (QCM), Surface Acoustic Wave (SAW) and fluorescence. The multi-sensors chamber was designed and optimized to guaranty an efficient fluidic repartition on each sensor to assure the suitable responses of sensors. A laptop controls the device. An algorithm has been specifically developed to detect and identify gas nature. On 33 experimentations with various explosives or interferents, the preliminaries results have shown the detection and the identification in about 1 min.
