| Abstract: | A method of interference correction for nondispersive infrared multi-component gas analysis was described.According to the successive integral gas absorption models and methods,the influence of temperature and air pressure on the integral line strengths and linetype was considered,and based on Lorentz detuning linetypes,the absorption cross sections and response coefficients of H2O,CO2,CO,and NO on each filter channel were obtained.The four dimension linear regression equations for interference correction w... |
