Emerson has announced the release of the Rosemount CT5100 continuous gas analyser — a hybrid analyser that combines tunable diode laser (TDL) and quantum cascade laser (QCL) measurement technologies for process gas analysis and emissions monitoring. The CT5100 can detect down to sub ppm level for a range of components, while simplifying operation and reducing costs.

The CT5100 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 CT5100 operates with no consumables, no in-field enclosure and a simplified sampling system that does not require any gas conditioning to remove moisture. The analyser is suitable for process gas analysis, continuous emissions monitoring and ammonia slip applications.

The CT5100 is a combination of advanced technology, high reliability and rugged design. Its ‘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 laser chirp 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.
