Emerson, a global manufacturing and technology company, has introduced a new continuous analyser to meet the expanding needs for accurate and cost-effective gas analysis and emissions monitoring systems.

The modular and scalable design of the RosemountTM CT5400 can incorporate up to six high-resolution laser modules and can detect, measure and monitor up to 12 critical components simultaneously.

The new device combines tunable diode laser (TDL) and quantum cascade laser (QCL) technologies in a single instrument, eliminating the need for multiple analysers, and it uses a patented ‘laser chirp’ to provide high-resolution spectroscopy which detects and identifies molecules in both the near and mid-infrared range of spectroscopic light.

Dr. Ruth Lindley, Product Manager for Emerson QCL analysers, explained, “By using the chirp methodology, 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.”

“In this way, the CT4500 offers plant managers and analyser operators greater peace of mind.”

The CT4500 rack-mounted analyser is designed for process applications, continuous emissions monitoring systems (CEMS) and continuous ambient monitoring systems (CAMS).
