FIELD: explosives.
SUBSTANCE: invention can be used during creation of instruments for detection of trace quantities of explosives used for ensuring the safety of air, automobile, water railway transport, production, office, accommodation and other facilities. Explosive detection method involves formation on the surface of molybdenum emitter of surface-ionisation detector of oxide film by heating the emitter in laminar air flow flowing off the emitter, at the specified flow rate required for analysis, supply to it of the air and analysed gas and measurement of ion current of ionisation process, cooling of analysed gas and air with their further supply to chemiluminescent indicator and measurement of luminescence using optic-electronic method and comparison of the shape of obtained measurement signals; in addition, availability of explosives is determined at the similar shape of obtained signals.
EFFECT: invention is meant for high-sensitivity detection of explosives.
