FIELD: electricity.
SUBSTANCE: invention relates to the field of spectrometry and can be used for the analysis of aerosols. Portable ion mobility spectrometry apparatus (1) for detecting an aerosol and a method for using the apparatus are disclosed. Apparatus comprises ion mobility spectrometer (3), portable power source (5) carried by the apparatus for providing power to apparatus (1), inlet (7) for collecting a flow of air to be tested by spectrometer (3), heater (4) configured to heat the air to be tested to vapourise an aerosol carried by the air and controller (2) configured to control spectrometer (3) to obtain samples from the heated air. Controller is configured to increase heat output from heater (4) for a selected time period before obtaining samples from the heated air.
EFFECT: technical result is high information content of the received data.
