Method of chemical extraction of polar lipid from human biological medium and excretion during sample preparation and features of explosive scent forensic examination with its use. Methodical aspect

The article is devoted to the methodological aspects of using the method of the polar lipid chemical extraction from biological medium and human excretion during explosive scent forensic examination. The main results of scientific activity of research group for determining the characteristics of sources of human odorous traces. The authors consider the characteristic use of a new method of sample preparation during explosive scent forensic examination, particularly in identifying diagnostic feature of the existence of human odorous traces in the sample under study by instrumental method thinlayer chromatography. The authors give many examples of successful practical using the chemical extraction method in the investigation of particularly serious crimes of previous years which caused a great public outcry.
