摘要
The invention relates to the field of integrated control of the people on crossings and can be used for biometric identification and gas analytical detection of trace amounts of substances to be controlled (eg explosive drugs) on the hands of human hands. The technical result of the present utility model is to automate and improve the efficiency of detection of trace amounts of controlled substances on the hands, increasing the sensitivity and reliability of the detection of traces of harmful substances with simultaneous biometric verification of a person on the hand geometry, which is achieved by an automatic identification of a person by personal code and biometric the parameters of the hand, automatic fixing of the hand on the sample plate, large quantities of m substance by increasing the surface under study, the test air-insulated from the outside environment protection flap, before moving the gas analysis of the gas analyzer to the sample plate to the desired distance, as well as easy replacement of contaminated vapors of dangerous substances sampling plate and analyzer.
