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