ABSTRACT:
A method and apparatus for infrared gas analysis are provided. The method includes measuring a concentration of a component in the sample gas, and measuring a concentration of water in the sample gas. The component concentration measurement is corrected with respect to water interference at a zero point. The component concentration measurement is further corrected with respect to water influence in coexistence to determine a corrected measurement that is corrected with respect to water interference at the zero point and water influence in coexistence.
