X-Ray Fluorescence: Chemical Characterization of Materials by X-Ray Spectrometry

2022
X-ray fluorescence techniques are widespread since the half of the last century for chemical investigation on rocks, minerals, industrial products, construction materials, precious materials, environmental pollutants, metals, paints, etc. Actually, they can be used to analyse almost every kind of solids and in many cases also liquid or gelatinous ...

Atomic Spectrometry Update—Atomic Mass Spectrometry and X-Ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1992
The large number of papers covered in this year's review emphasizes the strong developments which continue in atomic mass and X-ray fluorescence spectrometries. Although much of the effort is aimed at improving existing technology and methodology, new and innovative instrumentation is also being developed in a number of fields.

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 ...
