Abstract
A gas analysis apparatus includes: a first reflector that reflects measurement light from a light emitting unit disposed outside a gas flue wall and transmitted through a sample gas. A light receiving unit outside the gas flue wall receives measurement light reflected by the first reflector. A second reflector outside the gas flue wall reflects measurement light toward the light receiving unit. A computing unit analyzes sample gas by allowing the measurement light to be reflected by the first reflector and performs correction or calibration of the gas analysis apparatus using known substances within an associated containing unit along the light path between the light emitting unit and the second reflector by allowing measurement light to be reflected by the second reflector. A switching unit outside the gas flue wall selectively removes or inserts the second reflector from the light path during component concentration analysis and correction or calibration, respectively.
