Abstract
The invention relates to a method for analyzing gas by an optical method, according to which a gas sample, comprising gaseous species for which it is desired to determine the quantity, is subjected to an illuminating radiation generated by a light source. The method comprises detecting a radiation having crossed the gas, by means of a light sensor. According to the invention, the light source produces different successive illuminations, such that at each illumination, the spectrum of the illuminating radiation varies. During each illumination, the intensity of the radiation detected by the light sensor is recorded. A processor can estimate a quantity of each gaseous species as a function of the respective intensities measured during each illumination. The invention also relates to a gas analysis device implementing the method.
