ABSTRACT:
The invention relates to a method for the spectral analysis of metal samples with the following steps:a. Recording of a spectrum of an unknown sample with a number of preset excitation parameters,b. Comparison of the spectrum with stored spectra of a number of control samples,c. Determination of the control sample with the best concordance of spectra,d. Setting of the excitation parameters, which are stored for the best and closest control sample determined in step c,e. Recording of the spectrum of the unknown sample with the excitation parameters set in step d,f. Calculation of the intensity ratios of the analysis lines stored for the control sample and the internal standards of the spectrum recorded in step e.
