Emerson Rosemount CT4400 Continuous Gas Analyzer
Emerson presents the Rosemount CT4400 Continuous Gas Analyzer, a purpose-built quantum cascade laser (QCL) and tunable diode laser (TDL) analyser designed to help plants reduce ownership costs and report emissions accurately. The analyser measures standard components such as nitric oxide, nitrogen dioxide, sulfur dioxide, carbon monoxide, carbon dioxide and oxygen.
Optimised for cold and dry applications running at ambient pressure, the analyser offers the benefits of QCL/TDL technology, including high sensitivity, accuracy, improved stability and low-drift performance in a configuration that allows fast, easy integration into existing plant infrastructure.
Because the system can hold up to four laser modules, it can measure up to seven application-specific gas components simultaneously, providing flexibility in continuous emissions monitoring systems applications.
The Rosemount CT4400 employs Emerson’s QCL technology, which detects gas molecules in near- and mid-infrared wavelengths. 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 highly accurate and stable down to sub-ppm concentrations.
