Chemical agent sensors

Chemical. Exquisitely sensitive chemical agent sensors are available, but work best under laboratory conditions. Environmental chemical sensors suffer many of the same issues as biological detectors. They lack sensitivity, are not sufficiently mobile or flexible, and require trained users. Several types of chemical detectors are in use and are mentioned above. [Pg.49]

A detection scheme is a system that detects the agent, correctly identifies the agent, and defines the area of exposure. A number of different technologies are available today to detect chemical agents. Sensors are primarily designed to... [Pg.43]

Sensors that operate on the basis of interactive chemical surfaces are chosen for discussion here because they are likely candidates for the detection of chemical agents. However, many other sensor types are possible. [Pg.28]

Acoustic wave sensors are also used to detect nerve and blister agents. The surface acoustic wave chemical agent detector (SAW Mini-CAD) is a commercially available, pocket-sized instrument that can monitor for trace levels of toxic vapors of sulfur-based mustard agents (e.g., distilled mustard) and G nerve agents (e.g., tabun, sarin, soman) with a high degree of specificity. Colorimetric tubes are the... [Pg.162]

Chemoselective hydrogen-bonded acid polymers are at the heart of many electronic nose chemical point detection sensor systems. These polymers selectively adsorb chemical agents or explosives over extended periods of time (minutes, hours, days). Relatively thick polymer films and/or hyperporous structures allow rapid vapor sorption. Material properties are selected to allow vapor sorption, but not desorption, at ambient conditions. Heating allows the trapped agent to be released for analyses. [Pg.168]
