Air analysis with quick, reliable results
Abstract
Portable infrared gas analyzers useful for rapid qualitative/quantitative analyses of a wide variety of industrial gases with characteristic IR fingerprints are described, with a brief review of IR absorption spectroscopy principles. Examples of utilization of the MIRAN-1A 'Supernose' gas analyzer in leak detection, area concentration mapping, stack monitoring, time-weighted averaging, and specific problems are cited. Employee protection for chronic cumulative exposure to toxic agents and hazardous concentrations is described. The fail-safe feature of interference monitoring, with readings never lower than actual, is mentioned. Improvements in IR gas analyzers derived from actual industrial contamination events are cited. MIRAN-201 Multi-Point Infrared Monitor built-in circuits for high-level alarm, flow failure, and error annunciation are mentioned.
