Abstract

PURPOSE:To achieve a higher measuring stability, by computing the density of a gas based on a subtracted value between a comparison signal and a measuring signal and that between the comparison signal and an interfering signal to remove interference even when several interfering components exist. CONSTITUTION:As a light chopper 6 rotates, infrared rays emitted from a light source 2 are introduced into a comparison cell 3, a sample gas cell 4 and an interfering gas cell 5 sequentially. The light transmitted through the cells is condensed with a condenser 7 to be incident on a detector 8 sequentially. A detection signal detected with the detector 8 is stored into a memory 94 at a comparatively computing section 9 as comparison signal, measuring signal and interfering signal. The density of a sample component is calculated based on a difference between the comparison signal and the measuring signal while the density of an interfering component is done based on a difference between the measuring signal and the interfering signal and based on the differences thus obtained, the density of a component to be measured free of effect of the interfering component is calculated.
