Laser-induced breakdown spectroscopy is evaluated as a means of detecting the fire suppressants CF3Br, C3F7H, and CF4 and the refrigerant C2F4H2. The feasibility of employing laser-induced breakdown spectroscopy for time- and space-resolved measurement of these agents during use, storage, and recharge is discussed. Data are presented that demonstrate the conditions necessary for optimal detection of these chemicals.
