Cobalt ion-enhanced photochemical vapor generation in a mixed acid medium for sensitive detection of tellurium(iv) by atomic fluorescence spectrometry

, 2020
A method of cobalt ion assisted enhancement of photochemical vapor generation-atomic fluorescence spectrometry (PVG-AFS) was proposed for sensitive determination of ultratrace tellurium(IV).

Atomic Spectrometry Update—Atomic Mass Spectrometry and X-Ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1995
The large number of papers covered in this year's review emphasizes the strong developments which continue in atomic mass and X-ray fluorescence spectrometries. Although much of the effort is aimed at improving existing technology and methodology, new and innovative instrumentation is also being developed in a number of fields.

Atomic absorption, atomic fluorescence, and flame emission spectrometry

Analytical Chemistry, 1988
You don't know much and that's a fact. While this originates from Alice in Wonderland, it adequately describes the feeling at the end of a biennium when 2000+ articles are perused before compiling this review. During the last two years articles have appeared which solved problems that experience and history suggest never were a problem, while other ...

Studies in atomic fluorescence spectrometry

Analytica Chimica Acta, 1973
Abstract The simple inexpensive adaptation of a conventional flame spectrometer for sensitive measurements of atomic fluorescence signals is described. The modifications include a home-built lock-in amplifier and pre-amplifier, high-frequency modulation of electrodeless discharge tubes, an optical system with 3 mirrors and a lens, and argon ...

Atomic Fluorescence Flame Spectrometry

Applied Spectroscopy Reviews, 1967
Fluorescence flame spectrometry is based upon the absorption of radiation by an atomic vapor to produce excited atoms, and the measurement of the radiation emitted when a fraction of these excited atoms lose their energy by a radiational process or processes called atomic fluorescence. Mitchell and Zemansky [1] and Pringsheim [2] have discussed much of
