Compact Size Explosives Detector with Ultra Fast Response and High Sensitivity and Method for Detecting Explosives

摘要

A system and methodology for semi-selective Infra-Red sampling and detection of explosive traces is described. The detection system combines the advanced Infra-Red sampling technique, capable to sample even non-volatile explosives in vapor mode with sensitive and interfering compounds extremely resistant analytical unit for reliable detection of all explosive compounds. All presented technology is designed to create ultra-miniature pocket-sized, ultra-fast detection system.
