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

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 ...
