GDA 2
The GDA 2 was designed to detect and monitor most common hazardous gases including chemical warfare agents (CWA). The main detector, an ion-mobility spectrometer (IMS) detects ammonia, inorganic sour gases, small chlorinated molecules, as well as other electropositive and electronegative compounds. The IMS is also used in the CWA detection mode. The IMS functions as part of an array that includes a photoionization detector (PID), an electrochemical cell and two metal oxide sensors. With the additional detectors the GDA is able to evaluate other toxic compounds, including benzene, phosgene, vinyl chloride, and chlorobenzene.
