Air-Monitoring System

The open-path Fourier transform infrared (FTIR) air-monitoring system simultaneously detects, identifies and measures a wide range of contaminants at levels from percent to parts per billion. Each system includes an interferometer that is equipped with user-selected beamsplitters and detectors. The analyzer is coupled to a control PC via standard ribbon cable or long-range fiber optic link. A continuous sampling path up to 1,000 m long is standard; for extended sample paths, the FTIR can be mounted to a rugged 10-in. Newtonian telescope supported by a tripod. A high-energy infrared source module on the opposite end of the sample path completes the system. Weighing 40 lb and measuring 8 in. W × 14 in. D × 8 in. H, the compact interferometer module is easy to transport and can be powered by a 12-V car battery. An optional lightweight sheetmetal version of the FTIR is available with a compact 3-in. telescope. The system is suitable for industrial stack monitoring, fenceline monitoring, hazardous event response, analysis of chemical warfare agents on the battlefield, and environmental research (such as volcanic gas analysis).
