Chemiluminescence Detectors Most common explosives materials contain nitrogen (N) in the form of either nitro (NO2) or nitrate (NO3) groups. • Chemiluminescence reaction scheme for explosives detection involves infrared radiation (IR) light emission from excited-state nitrogen compounds. • All that can be said is that a nitrogen-containing molecule was present that decomposed to yield NO, and such molecules are found in explosives and taggants but also in fertilizers, some perfumes, and other common materials. • So a GC Column is typically fixed on the front end •
