analüütiline meetod, mis koosneb (a) ergastamisest, (b) emissioonspektri mõõtmisest, (c) mõõdetud spektrijoonte intensiivsuste teisendamine kontsentratsioonideks, X-ray spectroscopy consists of three steps: (a) excitation to produce emission lines characteristic of the elements in the material, (b) measurement of their intensity, and (c) conversion of X-ray intensity to concentration by a calibration procedure which may include correction for matrix effects .
