Tunable diode laser absorption spectroscopy (TDLAS)
A laser-based optical technique to detect and measure the concentration of impurities in process gas streams to boost your plant safety and efficiency
TDLAS provides on-line, real-time measurements of impurities in process gas streams with low parts-per-million sensitivity. The technology is widely used by gas plant operators for measurements of moisture (H2O), carbon dioxide (CO2), hydrogen sulfide (H2S), and more in gas processes and pipelines. By delivering accurate and robust measurements with fast response times, TDLAS offers higher plant safety, efficiency, and availability with low cost of operation.
