The detection performance of a portable surface acoustic wave sensor array chemical agent detector (JCAD, BAE Systems) was investigated with nerve gases, blister agents, and blood agents. The vapors of sarin, soman, tabun and lewisite l (low level) were recognized as "NERV (nerve agent)" after about 10 sec of sampling, and the detection limits were about 30, 50, 100 and 300 mg/m^3, respectively. The vapors of mustard gas and lewisite 1 (high level) were recognized as "BL (blister agent)" after about 10 sec sampling, and the detection limit for mustard gas was about 40 mg/m^3. The gases of hydrogen cyanide and cyanogen chloride were recognized as "BLOD (blood agent)" after about 2 min sampling, and the detection limits were about 30 and 1000 mg/m^3, respectively. Many solvents, such as methanol, dichloromethane and ammonia, were also recognized as chemical-warfare agents.
