Book Description
A rapid and inexpensive x-ray fluorescence spectroscopic method for the analysis of particulate contaminants has been developed. The method employs the collection of the particulates by filtration followed by x-ray fluorescence analysis of the filter. A unique method for the preparation of standard materials on filters for calibration of the x-ray spectrometer has been developed. Linear response over 2 orders of magnitude is routine. The sensitivity is in the parts per million range. The precision and accuracy is about 3 to 5 percent. The method is currently being used to determine contamination in fuels and to correlate the contamination and wear metal particulates in lubricants with engine wear. A large number of turbine fuels and lubricants have been analyzed and the data obtained have correlated to field performance. (Author).

Book Description
X-ray spectrometry (XRF) is a versatile instrumental method for elemental analysis in a wide variety of materials. The performance of three different XRF systems will be compared: a high power wavelength dispersive x-ray spectrometer (WDXRF), a low-power WDXRF, and a bench-top energy dispersive instrument (EDXRF).

Book Description
Henry Moseley was perhaps the father of the X-ray fluorescence (XRF) technique. He was the first to build an X-ray tube that could be used to bombard samples with high-energy electrons. In 1925, Coster and Nishina [1] began using the X-rays coming from the bombardment of an electrode to excite an actual sample. Glocker and Schreiber [2] attempted to use the infant technique for quantitative analysis in 1928. Poor quality detector tubes made this nearly impossible until the late 1940s. The first commercially available instruments were offered in the 1950s. In 1970, the lithium drifted silicon detector was developed and it is still in use today!.

Book Description
Hardbound. In Volume IIC of the series, G.L. Macdonald contributed a chapter on X-Ray Spectrometry in which the principles of X-ray fluorescence analysis were presented with great clarity. Since that contribution appeared in 1971 tremendous developments have taken place with one of the most important new features being the appearance of energy-dispersive methods.This new volume gives a detailed and up-to-date account of this important technique. It covers the various physical and technical problems associated with this analytical method, with emphasis on explaining the interferences due to matrix and particle size effects. Methods for overcoming these interferences are described and other sources of errors and the processing of measurement data are discussed. Also described are numerous applications of EDXRF analysis in a variety of fields including geological prospecting and mining, trace element analysis, biology, medicine, environmental pollution con

Book Description
Micro-X-ray fluorescence offers the possibility for a position- sensitive and non-destructive analysis that can be used for the analysis of non-homogeneous materials and layer systems. This analytical technique has shown a dynamic development in the last 15 years and is used for the analysis of small particles, inclusions, of elemental distributions for a wide range of different applications both in research and quality control. The first experiments were performed on synchrotrons but there is a requirement for laboratory instruments which offers a fast and immediate access for analytical results. The book discuss the main components of a μ-XRF instrument and the different measurement modes, it gives an overview about the various instruments types, considers the special requirements for quantification of non-homogeneous materials and presents a wide range of application for single point and multi-point analysis as well as for distribution analysis in one, two and three dimensions.
