Emerson Rosemount CT5100 hybrid laser analyser for continuous gas analysis

Click2Contact

The Rosemount CT5100 continuous gas analyser is claimed to be the world’s only hybrid analyser to combine tunable diode laser (TDL) and quantum cascade laser (QCL) measurement technologies for process gas analysis and emissions monitoring.

The product can detect down to sub-ppm level for a range of components while simplifying operation and reducing costs. It can measure up to 12 critical component gases and potential pollutants simultaneously within a single system, meeting local, state, national and international regulatory requirements.

The device operates with no consumables, no in-field enclosure and a simplified sampling system that does not require any gas conditioning to remove moisture. Suitable for process gas analysis, continuous emissions monitoring and ammonia slip applications, it provides subsecond response time for precise measurement of complex gases and emissions to ensure regulatory compliance and prevent costly fines or unexpected shutdowns.

The analyser’s ‘laser chirp’ technique expands gas analysis in both the near- and mid-infrared range, enhancing process insight, improving overall gas analysis sensitivity and selectivity, removing cross interference and reducing response time. The technique produces sharp, well-defined peaks from high-resolution spectroscopy that enable specificity of identified components with minimum interference and without filtration, reference cells or chemometric manipulations.

Solid-state components and a modular design, with up to six lasers inside a single enclosure, simplify start-up and commissioning and reduce field maintenance costs during the analyser’s life cycle.
