Emerson continuous gas analyzer measures sub-parts-per-million concentrations
The Rosemount CT4400 continuous gas analyzer is a quantum-cascade laser (QCL) and tunable diode laser (TDL) analyzer, designed for plants to report emissions in environmental monitoring applications measuring standard components. The QCL system uses a patented laser chirp technique that detects individual gas species, measuring sub-parts-per-million concentrations.
