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.

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 ...

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

A New, simple atom reservoir for atomic fluorescence spectrometry

Analytica Chimica Acta, 1969
Abstract The disadvantages of flames as atomizers are summarized, and a new, simple and efficient means of atomization of samples is proposed. The solution on a platinum loop is vaporized by electrical heating into an argon stream. Limits of detection were 10-14 g for cadmium, 10-8 g for mercury, and 10-7 g for gallium. Linear calibration graphs were

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 ...

Studies in atomic fluorescence spectrometry

Analytica Chimica Acta, 1975
Abstract A method has been developed for the determination of tin in steel based on the atomic fluorescence of tin at the 303.4-nm line in an argon-separated air-acetylene flame (detection limit 0.05 p.p.m.) or argon-oxygen-hydrogen flame (detection limit 0.01 p.p.m.).

Interferences in hydride atomization studied by atomic absorption and atomic fluorescence spectrometry

Spectrochimica Acta Part B: Atomic Spectroscopy, 1996
Abstract A hydride atomizer able to operate in the flame-in-tube mode and in the miniature diffusion flame mode was used to investigate interferences of arsenic in selenium atomization. A twin-channel continuous flow hydride generator was utilized to eliminate liquid phase interferences.
