Chemical detection detectors

Environics produces chemical sensors, detectors, and detection systems for protection of people, the environment, and for space research. Their sales network covers more than thirty countries all over the world. Currently, in the United States, they are marketing the ChemPro 100 for both military and civil defense, as well as other chemical detection gear. 

Individual Chemical Agent Detector (ICAD) A miniature lightweight chemical agent detector that can be worn by an individual. It detects and alarms to nerve, blood, choking, and blister agents and is intended for a variety of applications. It may be used as a point detector. 

Joint Chemical Agent Detector (JCAD) This detector will employ surface acoustic wave technology to detect nerve and blister agents. It will also allow detection of new forms of nerve agents. 

M256-Series Chemical Agent Detector Kit A kit used by military personnel to detect and identify field concentrations of nerve, blister or blood agent vapors. The kit consists of twelve samplers/detectors and a packet of M8 detector paper. It is used at the squad, crew or section level to detect and identify field concentrations of nerve, blister or blood agents vapors. It is usually used to determine when it is safe to unmask, to locate and identify chemical hazards, and to monitor decontamination effectiveness. 

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... 

Joint Service Lightweight Standoff Chemical Agent Detector (JSLSCAD). The JSLSCAD is a passive, IR detection unit employing FTIR Spectrometry. The device is designed to detect nerve and blister vapor clouds at a distance of up to 5 km. 

A good practice is to monitor the workspace inside the fume cupboard with a continuous handheld or tabletop chemical agent detector, if such a device is available. There are several models commercially available based on ion mobility, flame photometric, enzymatic, or photoacoustic detection (9). 

On-column UV absorbance detection is by far the most common method of detection in CE today. Many compounds of interest absorb light to some extent in the UV region without any chemical modification. Detector components are fairly robust and inexpensive, and little operator skill is required. For these reasons, most commercial CE instruments are equipped with a standard UV absorbance detector. However, as absorbance signals are directly proportional to the optical pathlength (Beer s Law), the 10-100 xm internal diameter of capillaries used in CE yield rather disappointing detection limits in the range of 10-5-10-7M (7). 

ISCAD The IMS/SAW chemical agent detector (ISCAD) is an NRL program outside the Joint CBD Program. It strives for ultralow false-alarm rates by integrating two CW point detection technologies (IMS and SAW) that have orthogonal principles of operation. The objective is a handheld chemical detector with subsecond equilibrated chemical detection at threat levels for survey mode and vehicular applications. The ISCAD incorporates NRL s pCAD, which dramatically improves SAW signal kinetics and tolerance to environmental effects.
