Abstract
A method of calibrating a gas analysis apparatus that measures the moisture concentration in a gas using a radiating unit includes a moisture concentration measurement value calibrated based on the relationship between the intensity of an absorption spectrum of moisture of a concentration to be measured and the intensity of an absorption spectrum of an other component gas that can be measured by the radiating unit, for which the relationship to the intensity of the absorption spectrum of moisture of the measured prescribed concentration is known, and based on the intensity of an absorption spectrum obtained by measuring the other component gas.
