PURPOSE:To compensate an interference portion automatically and in a short time by a method wherein the interference portion of a component to be measured which overlaps the output of a memorized component to be measured is determined from the rate (K value) of the interference of the component to be measured in another component to be measured which is calculated from the output of the interference portion and the output of the component to be measured. CONSTITUTION:In the first step, the apparatus is set in a test mode. First, the outputs E1-En of detectors D1-Dn are memorized respectively. Then, the rate (K value) of the interference of a test gas in the output of another detector is computed and memorized for each detector. In the second step, the apparatus is set in a measurement mode. First the outputs E1'-En' of the detectors D1-Dn are memorized respectively. Then, the output E/K of an interference portion contained in each of the outputs E1'-En' is determined on the basis of said memorized rate of interference. Subsequently, the output of the interference portion is subtracted from each of the outputs E1'-En' determined before, and thus the outputs EM1-EMn of components to be measured which are free from interference portions are calculated. |
