  The detection of explosives and drugs in hard-to-reach places is a
considerable challenge. We report the development and initial experimental
characterization of the air analysis system that includes Field Asymmetric Ion
Mobility Spectrometer (FAIMS), array of the semiconductor gas sensors and is
installed on multicopter. The system was developed based on the commercially
available DJI Matrix 100 platform. For data collection and communication with
operator, the special compact computer (Intel Compute Stick) was installed
onboard. The total weight of the system was 3.3 kg. The system allows the 15
minutes flight and provide the remote access to the obtained data. The
developed system can be effectively used for the detection of impurities in the
air, ecology monitoring, detection of chemical warfare agents and explosives,
what is especially important in light of recent terroristic attacks. The
capabilities of the system was tested on the several explosives such as
trinitrotoluene and nitro powder.
