Real-time Detection and Identification of Chemical Warfare Agents, Toxic Industrial Gases and Explosives with the Hand-held, Multi-sensor GDA2

Airsense Analytics (Germany) has designed in cooperation with First Response teams a portable hazardous Gas Detector Array (GDA2) for the detection and the identification of CWA’s like Nerve, Blister, Blood and Choking agents and a broad range of TIC’s (ETW, AEGL, ERPG, ITF-25 list, etc.).
Furthermore the GDA2 is able to detect some Explosives.
By using 4 different sensor-technologies like a Photo Ionization Detector (PID), an Ion Mobility Spectrometer (IMS), two semiconductor gas sensors and an electrochemical cell, simultaneously the GDA2 reduces false positives and achieves greatly extended far-superior
coverage of hazardous volatiles with more accuracy than single-detection technology. The released gases and CWA’s can be detected within seconds with detection limits from low ppb to high ppm concentration.
The GDA2 holds up to 3 different libraries each are customized and comprising up to 256 compounds. The first target of the GDA2 is safety: The user is warned when compounds are present – although compounds may not contain in the library that is currently active.
NEW: In real situations users encounter situations where the toxic gases might reach extremely high concentrations, such as explosion levels (in the %-range). Therefore Airsense has designed new procedures for the self protection of the detectors and an ex-proof design.
The GDA2 is the most enhanced chemical detector currently available. It is used by various first responder teams in chemical plants, semiconductor industry, fire brigades, military, Airports and Police worldwide.
