EXPLOSIVES DETECTOR Russian patent published in 2000 - IPC

FIELD: devices for detection of explosive in sample. SUBSTANCE: the presence of plastic explosive Semtex in a sample. such as a finger-print is detected by means of the Romanov spectroscopy. Active chemical ingredients of the Semtex plastic explosive have stable Romanov peaks on 885 cm^-1 and 874 cm^-1, respectively. Taking into account this fact, these peaks can be detected by the Romanov spectroscopic system with employment of a filter, having a narrow band of transmission centered on 880 cm^-1, and having a band of transmission equal to 20 cm^-1. Such a filter should be used in the Romanov system used for scanning of aviation boarding passes or in the Romanov microscope, which provides for reproduction of image of finger-prints. The device provides for detection of the most often used explosive within a relatively short period of time and in the presence of impurities in the sample. EFFECT: enhanced efficiency. 8 cl, 11 dwg, 1 tbl
