FIELD: analytical tool-making industry, in particular, analytical devices meant for detecting micro-concentrations of substances, possible use for detecting steams of explosives on documents, for example, passports, tickets, etc.
SUBSTANCE: device for controlling traces of explosives on documents contains heated desorber for mounting steam carrier, air pump and detector of analyzed steams of explosives, while desorber is made in form of document receiver, which consists of central chamber, wherein document being studied is positioned, and divided from it by air gaps by two side chambers with electric heaters mounted in them, while inputs of side chambers are connected to output of air pump, connected by input to atmosphere, and outputs of side chambers are connected through air gaps of central chamber to input of detector of analyzed steams.
EFFECT: accelerated detection of steams of explosives absorbed on documents while providing for safety of document.
