Emerson's Rosemount CT5400 Continuous Gas Analyzer is a hybrid, lased-based analyzer designed for gas processing and emission monitoring applications. Combining Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) technologies, the Rosemount CT5400 expands gas analysis to both the near and mid-infrared range, covering many gas species using a unique intra-pulse spectroscopic method. This technique enables real-time detection of up to ten different gases simultaneously in a single instrument, reducing cost of ownership, footprint and operational complexity while providing fast response time and sub-parts per million gas analysis.
