The Rosemount CT5400 continuous gas analyzer (photo) combines tunable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyzer, and uses a patented “laser chirp” to provide near-instant high-resolution spectroscopy to detect and identify a range of molecules in both the near- and mid-infrared range with an enhanced dynamic range from sub parts per million (ppm) to percent levels. Unlike traditional process-gas analyzers requiring continuous calibration and verification, and other single laser-based systems that are limited to measurement of one or two components, the modular and scalable design of the CT5400 can incorporate up to six high-resolution laser modules and can detect, measure, and monitor up to 12 critical components simultaneously. The CT5400 rack-mounted analyzer is designed for process applications, DeNOx/SCR, ammonium nitrate precursors, continuous emissions monitoring systems (CEMS), and continuous ambient monitoring systems (CAMS). — Emerson Process Management, Shakopee, Minn.
