METHOD OF LABELLING EXPLOSIVE SUBSTANCE Russian patent published in 2013 - IPC C06B23/00 G01N33/22 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of inspecting explosive substances and forensic identification preparations. The method of labelling an explosive substance involves adding a labelling composition to the explosive substance, said composition containing identifiers, the number of which is equal to the number of properties to the labelled. The identifiers used are a mixture of polyorganosiloxanes with different molecular chain lengths, wherein each property matches an identifier in form of a polyorganosiloxane with a corresponding molecular chain length and corresponding "exit time" (retention) on a chromatogram. Thus a "chemical barcode" is formed in the explosive substance, which is read from the chromatrogram based on the principle of the presence or absence of a component at a certain time of its "exit" (retention). The method is suitable for labelling mixed and separate explosive substances, as well as components thereof, for example inorganic oxidants, particularly ammonia nitrate.

EFFECT: method provides high reliability of identifying an explosive substance with a simple process of determining its code.
