FIELD: chemistry.
SUBSTANCE: device for residue low-volatile substance detection on fingers includes gas detector issuing alarm signal when a vapour of wanted substance is registered, heated gas channel connected to the gas detector input at one end, heater, adjustable current generator connected to the heater, push-button device, plate with push surface, fixed in the push-button device, with the other end of heated gas channel connected to the back side of push surface. Plate position sensor, which produces signal when the plate surface is pushed, and air and/or push surface temperature sensor can be connected to the gas detector and/or adjustable current generator.
EFFECT: significant simplification of human fingers examination process; automation of residue low-volatile substance detection process and reduction of examination time.
