DEVICE FOR DETECTION OF DANGEROUS SUBSTANCES ON HANDS OF PERSON OR DOCUMENTS Russian patent published in 2009 - IPC G01N25/36 

FIELD: physics.

SUBSTANCE: device for detection of dangerous substances on hands of person or documents contains substrate, airflow shaper over substrate, heater and one or several analysers of steams of dangerous substances in the form of spectrometer of the ionic mobility gain. The heater is executed in the form of one or several halogen valves located from below under the substrate, executed of thin leaf of metal with characteristic sizes thickness of 0.0002…0.001 from object of examination, inferior surface of substrate is supplied by coat with the variable absorption constant of radiant energy increasing from the central part of substrate to its edges. Thus the substrate is anchored on perimeter with possibility of its prompt replacement and supplied by the travel mechanism. On or over substrate it is erected one or several temperature sensing devices joined by a line of guidance with devices of insert-deenergising halogen valves.

EFFECT: increase of dangerous substances on hands of person or documents detection efficiency.
