COMPLEX FOR DETECTION OF EXPLOSIVE SUBSTANCE ON FINGERS DURING DACTILOGRAPHIC BIOMETRIC CHECK UP OF PERSON Russian patent published in 2010 - IPC G01N1/22 

FIELD: explosive substances.

SUBSTANCE: complex consists of gas-analyser-detector of explosive substances, of heater, of start-up mechanism, of contact plate with aperture and of system of person check up on base of dactylographic biometric scanner. The contact plate is chosen with temperature of melting exceeding temperature of explosive substances decomposition. Thickness of plate is 0.003-0.01 of person finger width. The plate is placed on or above working surface of reading block of dactylographic biometric scanner at height of 0-10 of plate thickness. Also the plate is equipped with mechanism of travelling into a module with the heater and gas-analyser-detector of explosive substances. The module with the heater and gas-analyser-detector of explosive substances is equipped with a device for plate cooling.

EFFECT: upgraded reliability of explosive substances detection at simultaneous dactylographic biometric check up of a person.
