Experimental spectral distribution versus Kramers' law for quantitative X‐ray fluorescence by the fundamental parameters method
Abstract
Quantitative X‐ray fluorescence analysis by the fundamental parameters method and the LAMA Program shows that the experimentally determined spectral distribution leads to accurate results whereas the continuous spectrum calculated from Kramers' Law often leads to relatively large errors. The primary characteristic line spectrum of a W tube at 45 kV may cause most of the fluorescent intensity, e.g. nearly all the Ni K and about 60% of Cr K.
