In response to the need for highly accurate, easy-to-use and cost-effective process gas analysis and emissions monitoring systems, Emerson has released the Rosemount CT5400 continuous gas analyser.
Combining tunable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyser, the CT5400 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 of spectroscopic light with an enhanced dynamic range from sub ppm to percent levels.
Unlike traditional process gas analysers requiring continuous calibration and verification, and other single laser-based systems which 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, eliminating the need for multiple analysers and sample handling systems.
The CT5400 rack-mount analyser is designed for process applications, DeNOX/SCR, ammonium nitrate precursors, continuous emissions monitoring systems (CEMS), and continuous ambient monitoring systems (CAMS).
Sharing many of the same measurement principles as the recently released Rosemount CT5100 analyser, which comes in a ruggedised Class 1 enclosure for hazardous area installations, the CT5400 is a cost-effective alternative for plants with an existing shelter or safe area application.
