Abstract
A method for compensating spectrum drift in a spectrometer having a radiation source, optical apparatus to split up a spectrum into spectral lines according to wavelengths of radiation from the radiation source, a number of detectors to receive partial spectra, and which are provided with respective pluralities of pixels to measure radiation intensity, and a catalog of spectral lines of different chemical elements that may be used as correction lines. The method may include generating and recording an emission spectrum of a sample; determining pixels receiving the maximum of the peaks for respective partial spectra and identifying respective peak positions for the peak maxima; for the respective peak positions, determining if there is a correction line within a predetermined maximum distance from the peak position, and if so, calculating a distance between the peak position and the correction line; and calculating a correction function for assignment of peak positions.
