[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.

Atomic-fluorescence and atomic-absorption spectrometry for chemical analysis

The Analyst, 1974
Atomic-absorption spectroscopy, which was first described in the literature in 1955, has now become widely accepted as a trace technique for the analysis of most metals. However, atomic fluorescence, which was first described in 1964, has not yet found widespread use.

Progress in laser excited atomic fluorescence spectrometry

TrAC Trends in Analytical Chemistry, 1998
Abstract Laser excited atomic fluorescence spectrometry, LEAFS, is a high sensitivity, high selectivity, atomic spectrometric technique. This paper reviews progress in LEAFS over the last several years, with emphasis on new lasers, new detectors, modifications to atomizers, and multi-element measurement approaches.

Atomic fluorescence spectrometry of mercury: principles and developments

Spectrochimica Acta Part B: Atomic Spectroscopy, 1995
Abstract Atomic fluorescence spectrometry (AFS) of mercury is very sensitive and the AFS system is an excellent detector for mercury analysis. The first part of this review covers the principles of determination of mercury by AFS. The second part delineates the loss and increase of mercury through its transfer between the gas and solution phases. The

Resonance monochromator in atomic-absorption and atomic-fluorescence spectrometry

Journal of Applied Spectroscopy, 1986
The purpose of this study was to find a means of realizing the potential possibilities of a resonance monitor in atomic-flourescence and atomic absorption spectrometry by eliminating intrinsic radiation. The atomic beam was obtained by using a furnace situated in a volume evacuated to 1.3.10/sup -3/ Pa.

Need for fundamental data in atomic fluorescence spectrometry

Spectrochimica Acta Part B: Atomic Spectroscopy, 1988
Abstract This paper discusses the needs for fundamental data in atomic fluorescence spectrometry and addresses the diagnostic and theoretical aspects, on the one hand, and the analytical aspects, on the other. Transition probabilities, collision cross sections for excitation and deexcitation, lifetimes, quantum efficiencies, and ionization and ...
