Atomic spectrometry update. X-ray fluorescence spectrometry

Journal of Analytical Atomic Spectrometry, 1998
This annual review of X-ray fluorescence covers developments over the period 2003–2004 in instrumentation and detectors, matrix correction and spectrum analysis procedures, X-ray optics and microfluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications, as assessed from the published literature.

Atomic Fluorescence Spectrometry

Applied Spectroscopy Reviews, 1973
Abstract In keeping with the nature of these reviews, this discussion of atomic fluorescence spectrometry is chiefly concerned with the experimental aspects of atomic fluorescence spectrometry and with its application to elemental analysis in the laboratory.

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

J. Anal. At. Spectrom., 1995
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.

Atomic absorption, atomic fluorescence, and flame emission spectrometry

Analytical Chemistry, 1988
You don't know much and that's a fact. While this originates from Alice in Wonderland, it adequately describes the feeling at the end of a biennium when 2000+ articles are perused before compiling this review. During the last two years articles have appeared which solved problems that experience and history suggest never were a problem, while other ...

Studies in atomic fluorescence spectrometry

Analytica Chimica Acta, 1973
Abstract The simple inexpensive adaptation of a conventional flame spectrometer for sensitive measurements of atomic fluorescence signals is described. The modifications include a home-built lock-in amplifier and pre-amplifier, high-frequency modulation of electrodeless discharge tubes, an optical system with 3 mirrors and a lens, and argon ...

Atomic Fluorescence Flame Spectrometry

Applied Spectroscopy Reviews, 1967
Fluorescence flame spectrometry is based upon the absorption of radiation by an atomic vapor to produce excited atoms, and the measurement of the radiation emitted when a fraction of these excited atoms lose their energy by a radiational process or processes called atomic fluorescence. Mitchell and Zemansky [1] and Pringsheim [2] have discussed much of

Pulsed Source Atomic Fluorescence Spectrometry

Applied Spectroscopy Reviews, 1973
Abstract Atomic fluorescence spectrometry was introduced as an analytical method in 1964 by Winefordner and Vickers [1], and since then, numerous papers have been published concerning the theoretical principles, instrumentation, methodology, and uses of the method.

Continuum Source Tungsten Coil Atomic Fluorescence Spectrometry

Applied Spectroscopy, 2011
A simple continuum source tungsten coil atomic fluorescence spectrometer is constructed and evaluated. The heart of the system is the atomizer: a low-cost tungsten filament extracted from a 150 W light bulb. The filament is resistively heated with a small, solid-state, constant-current power supply.

Atomic Spectrometry Update—Inorganic Mass Spectrometry and X-ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1988
This year's Update includes an extended mass spectrometry section based on full abstracts and covering fully this extensive area of analysis. The newly introduced instrumentation for Glow discharge MS and the combined MS techniques are particularly notable this year. The ICP-MS section continues to grow in line with the increasing number of instruments
