FIELD: physics.
SUBSTANCE: proposed method comprises processing the specimen with bar code by reagent and determining prescription of its application. Note here that reagent with boiling temperature not exceeding 100°C is used. Note also reagent may be represented by coolants, Freon, various hydrocarbons, alcohols, organic acids, aldehydes, ketones, cyclic organic compounds and mixes thereof, aspirin, carbo thienyl reagents and derivatives of benzaldehyde. Then, processed specimen is places into tight container for gas phase to be subjected to gas chromatography for gas phase analysis. Note here that area of chromatographic peaks allows to determine authentically the prescriptions.
EFFECT: expanded range of applications.
