High Precision Measurement of Spectroscopic Parameters of H2S at 6320 ~6350cm-1 Band
As a highly corrosive and highly toxic gas, hydrogen sulfide (H<sub>2</sub>S) is an important intermediate product or pollutant in many fields such as chemical industry, energy and environment. Accurate online measurement of its concentration is of great significance for process control and production safety. Tunable diode laser absorption spectroscopy (TDLAS), as a quantitative absorption spectroscopy technique, is suitable for high-precision on-line measurement of H<sub>2</sub>S concentrationdoi:10.7498/aps.72.20221855 fatcat:kl6ivkfbcndevf7oirzyzr37he
