Abstract:
Gas analyzer and method for measuring the concentration of a gas component in a sample gas, wherein the wavelength of the light of a wavelength-tunable light source is varied within periodically successive sampling intervals and, in the process, additionally modulated with a frequency to perform wavelength dependent sampling of an absorption line of a gas component to be measured in the sample gas.
