Abstract

To measure small gas concentrations by absorption spectroscopy, the wavelength of monochromatic light is adjusted to the absorption line of the gas molecule. According to Lambert-Beer’s absorption law, the absorption coefficient K of the gas can then be determined from the ratio of the radiant flux transmitted by the gas sample to the radiant flux without gas.1
