In response to the need for an easy-to-use process gas analysis and emissions monitoring system, Emerson has released the Rosemount CT5400 continuous gas analyser.

Combining tuneable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyser, the product uses a ‘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. The modular and scalable design of the device 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 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 Rosemount CT5100 analyser, it is a suitable alternative for plants with an existing shelter or safe area application.

By using the chirp methodology, the laser-based gas analyser has a quick response time and makes continuous measurements. Sub-second measurements give operators the ability to make adjustments to their processes and avoid upsets. The measurement is direct, or ‘first principle’, unlike traditional technologies where the measurements are inferred. This eliminates the need for frequent calibration, saving engineer time and reducing running costs.
