Abstract
The invention relates to a method and to a spectrometer for determining the concentration of a gas component, wherein a light source of the spectrometer is operated as in wavelength modulation spectroscopy (WMS). Thus a determination of the concentration can also take place in accordance with WMS and the measured data can, however, additionally be processed, namely a sorting takes place on the time axis, such that the concentration can be determined using the methods of direct absorption spectroscopy (DAS).
