Temperature correction method for gas concentration measurement based on TDLAS technology
Accurate detection of gas concentration is in urgent demand in the fields of atmospheric environmental pro-tection,industrial production control,and exhaust emission monitoring.Tunable diode laser absorption spectroscopy(TDLAS)is an important method for achieving accurate detection of gas concentration.However,temperature varia-tions bring significant errors to the accurate measurement of concentration,making temperature correction of the results essential.In this paper,the mechanism of temperature influence of gas concentration detection by TDLAS technology is described and the temperature influence correction methods for gas concentration measurement based on TDLAS tech-nology is focused on analyzing and summarizing,and the trend of its development is envisioned.
