X-ray fluorescence spectrometry

Journal of Geochemical Exploration, 1992
Abstract X-ray fluorescence analysis is a technique that is widely used for the determination of both major and trace elements in a wide variety of geological materials. In this review, the analytical characteristics of both wavelength and energy dispersive instrumentation are considered as well as operating and calibration procedures applicable to ...

X-ray fluorescence spectrometry of copper intermediates

Talanta, 1976
Iron, magnetite, copper, copper(II) oxide, calcium carbonate, sulphur, silicon dioxide and aluminium oxide as components of copper intermediates (concentrates, slags, mattes, calcines and fluxes) in powdered (300-400 mesh) binary mixtures obey the Lachance-Traill equation, so the coefficients alpha(AX) of interelement effects can easily be determined ...

Analysis of tungsten carbides by X-ray fluorescence spectrometry

Talanta, 1976
Five sample presentation techniques were examined for the X-ray fluorescence spectrometric analysis of tungsten carbide alloys in powder and cemented forms. Powder samples may be oxidized by air at 600 degrees before fusion (I), or preferably by lithium nitrate during fusion (II); the fusion is effected with lithium-lanthanum tetraborate followed by ...
