Types of Fluorescence Transitions in Atomic Fluorescence Spectrometry

Applied Spectroscopy, 1972
Since the discovery of atomic fluorescence as an analytical tool, various types of atomic fluorescence transitions have been utilized for analytical studies. Unfortunately, as a result of the rapid development of the technique, some confusion has resulted in the designation of atomic fluorescence transitions.

"Zeeman Electrothermal Atomizer Laser Excited Atomic Fluorescence Spectrometry"

Topical Meeting on Laser Applications to Chemical Analysis, 1987
The work of Bolshov et al. (1) demonstrated elemental limits of detection at the femtogram level (part-per-trillion in solution) using Laser Excited Atomic Fluorescence Spectrometry (LEAFS) in a graphite cup atomizer. We have now shown that these detection limits can be equaled by using a graphite tube atomizer.

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 ...

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.

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.

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.
