FTIR Air Monitoring System

The open path FTIR Air Monitoring System from MIDAC (USA) is compact, versatile, and rugged. Designed to detect, identify and measure a wide range of key contaminants simultaneously, it has been used in many different configurations to address a diverse list of applications. Analysis is onsite through a continuous sampling path of up to 1000 meters.

Whether the application is battlefield chemical warfare agent analysis, civilian hazardous event response, industrial stack and/or fenceline monitoring, rocket plume analysis, analysis or environmental research (such as volcanic gas analysis), the MIDAC AM System can provide continuous, unattached, near real-time detection at ppb to % levels for hundreds of chemicals.

Each system includes a rugged, sealed 0.5cm-1 resolution interferometer equipped with a choice of beamsplitters and detectors. The analyzer is coupled to a control PC via standard ribbon cable or long range fiber optic link. For extended sample paths, the FTIR can be mounted to a rugged, 10” Newtonian telescope with tripod. A high energy infrared source module on the opposite end of the sample path completes the system. Weighing approximately 40lbs. and measuring just 8” x 14” x 8” (WxDxH), the compact interferometer module is easy to transport and can be powered by a 12V car battery for complete freedom of movement. An optional lightweight sheet metal version of the FTIR is also available with a compact 3” telescope.
