EXPLOSIVE MARKING METHOD Russian patent published in 2017 - IPC C06B23/00 G01N33/22 

FIELD: blasting operations.

SUBSTANCE: invention relates to chemical methods of inspecting explosive substances and forensic identification preparations. Explosive marking method is introducing marking composition which contain identifiers in explosive material, the number of identifiers is equal to number of technical parameters subjected to marking. Mixture of polyorganosyloxanes with different molecular chain lengths is used as the identifiers, in each molecular chain each technical indicator matches an identifier in the form of a polyorganosiloxane with a corresponding molecular chain length and corresponding "exit time" (“retention”) on a chromatogram.

EFFECT: so in the composition of explosive element there is formed "chemical bar code", reading of which is carried out on chromatogram on the principle of presence or absence of component at the specified value of time of its "exit" (“retention”).
