STATE-OF-THE-ART OF EXPRESS ANALYTICAL METHODS OF RESEARCH OF MATERIAL OBJECTS IN CRIMINAL PROCESS

Abstract

The article shows what new possibilities can give the complex application of modern methods of express analysis of material evidence in revealing and proving the circumstances of the investigated event in a criminal proceeding by using modern advances in chemistry and other natural and technical sciences. The instruments for rapid analysis used in the investigation practice are considered, including gas analyzers, chemical test systems (SIGMA set), X-ray fluorescence analyzers («EXPERT Mobile»), electronic microscopes, mass-analyzers (EMAL). The EVD-3000, which is today the most recognized portable detector for explosives (including plastic explosives) and their traces, provides an analysis of the result within 15 seconds. Portable gas analyzer of explosives vapor "EHO-M" is used to study material objects at the scene, as well as the Kinovar analyzer and the "Molecule" portable set. To diagnose the presence of drugs, specially made rapid chemical "spray-tests" of the type "Narcotics identification kit" manufactured by "Becton Dickinson" (USA) are used. Incorporated in expert and investigative practice, the portable set of chemical reagents for express analysis of narcotics "SIGMA" is used to identify objects that contain suspicion of the content of narcotic substances. Portable X-ray fluorescence express analyzer for alloys "EXPERT Mobile" allows non-destructive operational analysis of material objects in the field. Mass-analyzers with laser source of ions EMAL, "SELMI" provide the possibility of simultaneous detection of several dozen elements without destroying material objects.
