Abstract:
The invention relates to a method for determining concentrations of absorbing gases by means of a spectroscopic measuring device, wherein wavelength-dependent measurement values for a light intensity are obtained and a wavelength-dependent measurement value function is represented based on these values. A wavelength-dependent theoretical function is defined, which includes as parameters a calibration parameter and the concentrations. The calibration parameter is defined as a function of a device parameter and a correction parameter that depends on the concentrations. A cycle comprising a sequence of steps is performed several times in a row, wherein in a first step a numerical value for the correction factor is calculated from stipulated assumed values of the concentrations, wherein in a second step the theoretical function is determined using the calculated numerical value, wherein in a third step values for the concentrations are obtained by a curve adjustment calculation between the theoretical function determined in the second step and the measurement value functions and are stipulated as new assumed values. The assumed values obtained in the third step of the last cycle are output as new measured values.
