Emerson has announced the release of the Rosemount CT5100 continuous gas analyser, which combines Tunable Diode Laser (TDL) and Quantum Cascade Laser (QCL) measurement technologies for process gas analysis and emissions monitoring. The CT5100 is the latest offering in the Emerson CT5000 series, providing the most comprehensive analysis as it can detect down to sub ppm level for a range of components, while simplifying operation and significantly reducing costs. Unlike traditional continuous gas analysers, the CT5100 can measure up to 12 critical component gases and potential pollutants simultaneously within a single system – meeting international regulatory requirements.
The CT5100 operates reliably with no consumables, no in-field enclosure, and a simplified sampling system that does not require any gas conditioning to remove moisture. The new gas analyser is ideally suited for process gas analysis, continuous emissions monitoring, and ammonia slip applications.
“The increase in regulatory requirements worldwide, along with the decrease in experienced personnel in industrial plants, have paved the way for the emergence of a new generation of faster, more accurate, and easier-to-use measurement technologies,” said Ruth Lindley, product manager for QCL analysers at Emerson. “The CT5100 represents an important next step in that direction, providing unmatched sub-second response time for precise, reliable measurement of complex gases and emissions to ensure regulatory compliance and prevent costly fines or unexpected shutdowns.”
The analyser is a unique 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.
“The CT5100 was designed to give the plant more for less,” said Dave McMillen, North America business development manager for Emerson’s Cascade laser analysers. “Solid-state components and the unique 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 lifecycle.”
