Emerson's Rosemount CT5100 Continuous Gas Analyzer is the first hybrid, laser-based analyzer developed for process gas analysis and emissions monitoring. The Rosemount CT5100 combines Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) technologies to provide fast, direct and highly selective and sensitive measurement of multiple gas components simultaneously. It is available in two variants: a certified system, housed in a purged and pressurized enclosure for hazardous area installations, and a non-certified system for use in non-hazardous areas. Both can house up to six lasers to measure up to 10 gas components in real time. The laser arrangement consolidates measurements into a single gas analyzer, reducing total cost of ownership.
