The analyser is designed to help plants reduce ownership costs and report emissions accurately in environmental monitoring applications measure standard components, such as nitric oxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), carbon dioxide (CO2), and oxygen (O2).
Optimised for cold and dry applications running at ambient pressure, the Rosemount CT4400 analyser offers the benefits of QCL/TDL technology, including high sensitivity, accuracy, improve stability, and low-drift performance in a configuration that allows fast, easy integration into existing plant infrastructure.
“Our customers are looking for a better way to measure emissions without the ongoing high costs or need for frequent calibration and complex sample preparation that requires NOx converters or ozone generators,” said Paul Miller, Managing Director for Rosemount Quantum Cascade laser analysers, Emerson Automation Solutions.
“The Rosemont CT4400 continuous gas analyser gives them an answer to their exact requirements in a configuration they can just plug into their existing systems and be off and running – at a lower cost than previously possible.”
“The reduced complexity of the system over what most companies are used to results in higher reliability and analyser availability with a lot less personnel time required,” Miller said.
The system can hold up to four laser modules, measure up to seven application-specific gas components simultaneously and provide flexibility in continuous emissions monitoring systems applications.
The system employs a patented laser chirp technique that enables detection of individual gas species, free from the cross-interference effects of other gas components in the stream, making the measurement accurate and stable.
