Emerson has launched the Rosemount CT5400 continuous gas analyser, which it says is in response to “the worldwide need for highly accurate, easy-to-use and cost-effective process gas analysis and emissions monitoring systems”.
The company says the CT5400 uniquely combines tunable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyser 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”.
Emerson added that unlike traditional process gas analysers requiring continuous calibration and verification, and other single laser-based systems which are limited to measurement of one or two components, the modular and scalable design of the CT5400 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.
Dr Ruth Lindley, product manager for Emerson QCL analysers, said the Rosemount laser-based gas analysers “have a significantly quicker response time and make continuous measurements. Sub-second measurements give operators the ability to make adjustments to their processes and avoid costly upsets that can develop into emergencies.”
