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

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 interference effects are reported for 27 elements, 6 acids and 4 organic liquids on the atomic fluorescence determination of tin with argon-hydrogen, argon-oxygen-hydrogen and argon-separated air-acetylene flames. The addition of1000 p.p.m. iron (III) eliminates most interferences from the elements but not from the acids.

Analytical Curves in Atomic Fluorescence Spectrometry

Applied Spectroscopy, 1972
The shapes of theoretical growth curves in atomic fluorescence spectrometry are calculated for several possible atomizer cell geometries, for several geometries of illumination measurement, for both line and continuum sources of excitation, and for several a parameter values.

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.

Atomic fluorescence spectrometry with laser excitation

Spectrochimica Acta Part B: Atomic Spectroscopy, 1981
Abstract A laser atomic fluorescence spectrometry for the detection of trace concentrations of the elements is described. The detection limits for Pb, Fe, Na, Pt, Ir, Eu, Cu, Ag, Co and Mn in aqueous solutions obtained at present are the best ones for the rapid spectral analytical methods.

Atomic spectrometry update. Advances in atomic emission, absorption and fluorescence spectrometry, and related techniques

Journal of Analytical Atomic Spectrometry, 2003
This review covers a relatively mature area of atomic spectrometry, hence there are fewer new developments than in other research fields. The review should be read in conjunction with the previous year’s review and with other related reviews in the series.

Electrothermal atomic-absorption and atomic-fluorescence spectrometry with a tungsten-coil atomizer

Talanta, 1987
A pulsed electrothermal atomizer of the tungsten-coil type and apparatus for its application in atomic-absorption and atomic-fluorescence spectrometry are described. A tungsten-coil atomizer is shown to be just as good as commercial electrothermal atomizers with regard to sensitivity and reproducibility, but to have better operating characteristics.

A Hot Wire Loop Atomizer for Atomic Fluorescence Spectrometry

Applied Spectroscopy, 1970
Samples containing Ag, Be, Bi, Cd, Cu, Ga, Hg, Mg, Pb, Tl, and Zn are vaporized from a tungsten or platinum loop into an argon stream and excited by radiation from electrodeless discharge tubes to produce atomic fluorescence. The integrated atomic fluorescence signals are independent of loop material and loop temperature, and nearly independent of ...

Laser-Excited Atomic Fluorescence Spectrometry

1981
It is quite appropriate that lasers should be utilized for atomic fluorescence spectrometry (AFS). Both share similar times of origin and development. During the 1960s, the laser was developed as a light source and AFS as a spectrometric technique. In 1971, with the advent of commercially available tunable dye lasers, laser-excited atomic fluorescence ...
