X-ray Fluorescence Spectrometry
This chapter covers the use of XRF spectrometry. A very brief introduction to the theory is given followed by a summary of the capabilities of wavelength and energy dispersive instruments. A discussion of physical and spectral interferences is then provided. The largest section of the chapter covers the methods of sample preparation.openaire +1 more source
Current Trends in X-Ray Fluorescence Spectrometry
Applied Spectroscopy, 1969Calculation methods for quantitative analysis, energy dispersion, and inhomogeneous samples are current areas in x-ray analysis which offer hope of reducing analysis costs. Other areas which extend the capabilities of x-ray analysis include improved analyzer crystals, diffraction gratings, and effects of valence on spectral lines.

Dilution method in x-ray fluorescence spectrometry
Microchemical Journal, 1978Abstract The Lachance-Traill method was modified to a dilution method that retains all the advantages of the original method plus it enables the determination of as many elements as one pleases and is far simpler mathematically. The method had been tested with determination of copper, molybdenum, zinc, and arsenic in copper intermediates.

Multielement x‐ray fluorescence spectrometry of solutions
X-Ray Spectrometry, 1980Abstract The theoretical relationships between fluorescence intensity and concentration have been used for the calculation of correction constants of the Lachance‐‐Traill and Rasberry‐‐Heinrich equation for systems of solutions. The constants have also been calculated by means of the multivariate least‐‐squares method.
