Gas analyzing apparatus

Abstract

A gas analyzing apparatus comprises a light source (34) emitting an infrared luminous flux; a sample cell (38) which is arranged such that a sample gas is introduced therein and the infrared luminous flux emitted from the light source (34) is transmitted therethrough; and detection means (10a, 10b) which contain absorbers and are arranged such that the infrared luminous flux transmitted through the sample cell (38) passes through the absorbers and an increase in pressure according to the temperature within each of their absorber containers raised upon absorption of the infrared luminous flux by each absorber is optically detected so as to measure, based on the increases in pressure, concentrations of ingredients to be measured in the sample gas, wherein, as the absorbers contained in the detection means (10a, 10b), gases having ingredients identical to the ingredients to be measured are used, respectively.
