Prototype NIST method detects and measures elusive hazards
Date:11/18/2009

ease the captured molecules for analysis.

Bruno found that the mass of the collected molecules increases with rising oven and sweep gas temperatures, offering a way to detect specific target molecules under particular field conditions. NIST researchers demonstrated the new method using several explosives, including the pure explosive TNT and the plastic explosive mixture C-4. Among other applications, NIST researchers have used the method to improve sampling and analysis of fire retardants in a car interior, a topic of interest because of concerns expressed by some that the "new car smell" may be a health hazard. They also are using the method to detect volatile protein decomposition products in spoiled meats. Environmental applications could include detection of pesticides deposited on soils subject to weathering effects.
