    Abstract: A concentration measurement method performed in a concentration measurement device including an electric unit having a light source and a photodetector, a fluid unit having a measurement cell through which a gas flows, and a processing circuit for calculating a concentration of the gas based on an intensity of a light passing through the measurement cell. The concentration measurement method includes a step of determining an absorption coefficient of the measurement gas using a reference absorption coefficient determined in association with the reference gas and a correction factor associated with the measurement gas, and a step of obtaining a concentration of the measurement gas flowing in the measurement cell using the absorption coefficient of the measurement gas. When the absorption peak wavelength of the measurement gas is longer than the peak wavelength of the light source, a reference gas having a longer absorption peak wavelength than the peak wavelength of the light source is used, and when the absorption peak wavelength of the measurement gas is shorter than the peak wavelength of the light source, a reference gas having a shorter absorption peak wavelength than the peak wavelength of the light source is used.

    Abstract: A gas analyzing apparatus includes first and second laser sources that output first and second laser lights, a laser controller that controls the first and second laser sources to vary wavelengths of the first and second laser lights in the respective predetermined wavelength ranges, an optical multiplexer that multiplexes the first and second laser lights to transmit the multiplexed laser light to a target gas, an optical receiver that receives the laser light transmitted through the target gas, and an analyzer that analyzes a temperature and/or a concentration of the target gas based on an electric signal output from the optical receiver. While varying the wavelengths of the laser lights, the laser controller controls amplitudes of the first and second laser lights to differ from each other and varies intensities of the first and second laser lights in the opposite direction.
