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

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.

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.

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.

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

[18] Atomic fluorescence spectrometry

1988
Publisher Summary Two practical approaches to atomic fluorescence are described in this chapter. The first concerns hollow cathode lamp excited AFS in the ICP. The second concerns the determination of mercury by cold vapor atomic fluorescence spectrometry.

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 ...
