X-ray fluorescence spectrometry with synchrotron radiation

Analytica Chimica Acta, 1985
Abstract X-ray fluorescence spectrometry (x.r.f.) can be done through excitation with synchrotron radiation. This permits multi-element determinations in the trace region with improved detection limits compared to conventional x.r.f. Detection limits are evaluated and compared with theoretically calculated values.

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.

Current Trends in X-Ray Fluorescence Spectrometry

Applied Spectroscopy, 1969
Calculation 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, 1978
Abstract 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.
