Abstract

A gas analysis system includes: a laser light source for emitting a laser light to be transmitted through an analysis target gas; a photodetector configured to receive the laser light transmitted through the analysis target gas, for outputting a signal corresponding to an emission intensity of the received laser light; a gas analysis apparatus for analyzing the analysis target gas on the basis of the signal outputted from the photodetector; a variable light attenuator disposed between the analysis target gas and the laser light source; a transmitted-light amount detector configured to evaluate a transmitted light amount of the laser light transmitted through the analysis target gas on the basis of the signal outputted from the photodetector; and an attenuation amount controller configured to control an attenuation amount of the variable light attenuator on the basis of the transmitted light amount of the laser light evaluated by the transmitted-light amount detector.
