Hybrid laser-based gas analyzer for CEMs
Emerson Automation Solutions
The new Rosemount CT4400 continuous gas analyzer (photo) is the said to be the world’s first purpose-built quantum cascade laser (QCL) and tunable diode laser (TDL) analyzer designed to help plants reduce ownership costs and report emissions accurately in environmental monitoring applications. The system measures standard components, such as NO, NO2, SO2, CO, CO2, and O2. Optimized for cold and dry applications running at ambient pressure, the CT4400 analyzer 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 great flexibility in continuous emissions monitoring systems (CEMs) applications. — Emerson Automation Solutions, Shakopee, Minn.
