Standardless quantitative X-ray fluorescence analysis of multielement samples of irregular form


Theoretical dependence of the relation of intensities of X-ray fluorescence lines of chemical elements on the relation of their contents in analyzed sample is offered. Influence of various experimental factors on parameters of the received model is considered. The way of the standardless quantitative X-ray fluorescence analysis of multielement samples with use of the offered calibration dependence is described. Adequacy and analytical advantages of the developed approach are shown during determination of element composition of metal alloy samples of irregular form.
Key words: standardless quantitative X-ray fluorescence analysis, relation of spectral line intensities, calibration function, samples of irregular form.
