X-ray fluorescence spectrometry
Journal of Analytical Atomic Spectrometry, 1999This annual review of X-ray fluorescence covers developments over the period 1999–2000 in instrumentation and detectors, matrix correction and spectrum analysis software, X-ray optics and microfluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications as assessed from the published literature.

X-ray fluorescence holography (XFH) is a method of atomic resolution holography which utilizes fluorescing atoms as a wave source or a monitor of the interference field within a crystal sample. It provides three-dimensional atomic images around a specified element and has a range of up to a few nm in real space.

X-ray fluorescence spectrometry
Journal of Geochemical Exploration, 1992Abstract 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 ...

The status of chemical analysis by X-ray fluorescence has developed from that of a laboratory curiosity in the decade 1940–50 to its current position as an almost universal method with, according to a recent estimate, over 8000 spectrometers in use throughout the world.

X-Ray fluorescence (XRF) is an emission spectroscopic method for the qualitative identification and quantitative determination of elements. With few exceptions, XRF provides no information concerning the chemical species in which the sought element is found.

Preconcentration and x-ray fluorescence
Analytica Chimica Acta, 1982Abstract X-ray fluorescence spectrometry after dithiocarbamate preconcentration is described for the determination of vanadium, nickel and iron in residual fuel oils and in small amounts of particulate emissions from oil-fired sources. After the sample has been decomposed by dry ashing or wet digestion, the metal constituents are concentrated as ...

Journal of Electron Spectroscopy and Related Phenomena, 2001
Abstract In the last decade, hard X-ray holography using an inside reference point has been developed for the study of 3D atomic arrangements in solids. Two types of this method are used: “normal holography” in which the atoms serve as sources of X-radiation and “inverse holography” in which the atoms detect the interference field originating from ...

Polarization of molecular x-ray fluorescence
Physical Review Letters, 1988Polarization of Cl K\ensuremath{\beta} x-ray fluorescence following selective excitation of gaseous ${\mathrm{CH}}_{3}$CL with synchrotron radiation is reported. The degree of polarization of the fluorescence depends sensitively on the chosen incident excitation energy in the Cl K-edge region.

X-ray fluorescence spectroscopy
Nuclear Instruments and Methods in Physics Research, 1983Abstract This is a general review of X-ray emission spectroscopy using synchrotron radiation from storage ring sources. Applications thus far have been to chemical analysis and to use of emission as a probe of absorption in dilute samples. One class of application combines the use of high resolution primary monochromator with a secondary spectrometer
