Rosemount CT5400 combines a tunable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyzer. The device uses a “laser chirp” to provide near-instant high resolution spectroscopy. It detects and identifies molecules in both the near- and mid-infrared range of spectroscopic light with an enhanced dynamic range from sub-ppm to percent levels. Unlike traditional process gas analyzers requiring continuous calibration and verification, or other single-laser-based systems that are limited to measurement of one or two components, the analyzer can incorporate up to six high resolution laser modules. It can detect, measure and monitor up to 12 critical components simultaneously, eliminating the need for multiple analyzers and sample-handling systems. The rack-mount analyzer is designed for process applications, DeNOX/SCR, ammonium nitrate precursors, continuous emissions monitoring systems (CEMS) and continuous ambient monitoring systems (CAMS).
