Emerson has released the Rosemount CT5100 continuous gas analyser, which is a hybrid analyser that combines tunable diode laser (TDL) and quantum cascade laser (QCL) measurement technologies for process gas analysis and emissions monitoring. It is suitable for process gas analysis, continuous emissions monitoring and ammonia slip applications.

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

The product operates with no consumables, no in-field enclosure and a simplified sampling system that does not require any gas conditioning to remove moisture. Its rugged design features a ‘laser chirp’ technique that 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.
