The fast identification of explosives, natcotics and other chemicals carried on board of ships or transported in containers
Abstrakt
The fast identification of explosives, narcotics and other chemicals carried on board of ships or transported in containers to the harbors is an important problem of maritime security. Raman spectroscopy is an advanced technique used in state-of-the art laboratories for fast identification of chemicals. No sample preparation is required, and identification can be carried out through transparent packing, such as plastic or glass, without opening it. Continuous progress in the field of photonics has resulted in commercial availability of low-power compact Raman spectrometers which can be integrated into portable systems. Such systems can be used by law enforcement personnel or first responders to identify solid and liquid chemical substances of concern in the scene, providing results within minutes.This paper present a portable Raman spectrometer designed and built by our team as well as discusses its operation and performance. The device uses separate modules with laser emitting at 785 nm and 355 nm, belonging to safety class IIIB. The modules work independently to reduce disturbances at the field measurements and to increase amount of investigated chemicals. The paper discusses efficiency of detection of a few example narcotics that can be mixed with typically used variety of adulterants/impurities. Similar data are presented for a few selected explosives. Further possible applications of the system are outlined as well.
