The solution of X-ray fluorescence spectrum quantitative
and qualitative analysis task has been proposed in the framework of
the united mathematical approach of spectrum full-profile treatment.
Experimental shapes of pure-element etalon profiles approximated by
splines have been chosen as a basis for the spectrum decomposition.
It has been shown that the detection limit of superimposed lines is
defined by the accuracy of the profile shape approximation and can
be reduced by difference treatment.
