    Abstract: An FTIR (Fourier transformation infrared) spectrometer is disclosed, wherein a validation/calibration of the spectrometer can be carried out in cyclically recurring intervals. Using at least two temporarily available gases, a reference spectrum with a zero gas and an absorption spectrum with a calibration gas are recorded. Substitute gases can be used during validation of the spectrometer as gas components, the substitute gases simulating actual measured gas components with respect to metrological properties.
