摘要: Detection of explosives is an important challenge for contemporary science and technology security systems. We present application NOx sensors equipped with concentrator in searching explosives. The using CRDS blue — violet diode lasers (410 nm) as well QCL (5.26 μm 4.53 μm) are described. detection method based either on reaction the to nitrogen oxides emitted by or produced during thermal decomposition explosive vapours. For TNT, PETN, RDX, HMX limit better than 1 ng has been achieved.
