Abstract
A gas analysis apparatus includes a calibration curve data storage section designed to store N types of calibration curve data which are previously created for N types of measurement target components and obtained by correcting influences of other N−1 types of measurement target components with respect to a concentration of each of the measurement target components, and a concentration calculation section designed to calculate a concentration of each of the measurement target components by using the N types of calibration curve data. When there exists a subthreshold component whose concentration calculated by the concentration calculation section is not more than a predetermined threshold value, the concentration calculation section calculates a concentration of each of the measurement target components other than the subthreshold component by using calibration curve data obtained without correcting an influence of the subthreshold component.
