FIELD: physics; measurement.
SUBSTANCE: invention relates to analytical instrumentation, in particular, to detection of ultratraces of hazardous substances - explosives, drugs, toxic substances. Technical effect is achieved as follows: device comprises a drift tube connected to the sample introduction device, which comprises a casing with nozzles for sample input and for gas bleeding from ionisation zone. The casing comprises a reciprocable target with nanostructured surface; continuously operating blower is positioned along the inlet and outlet nozzles axis; at the opposite inner end of the drift tube there is a collector connected to an amplifier; the amplifier output is connected to computer input. The target is provided with temperature controlling assembly.
EFFECT: enhanced sensitivity to traces of hazardous substances, express analysis possibility, reduced device dimensions.
