The advent of high peak power tunable visible and ultraviolet laser sources has made multiphoton ionization processes feasible. The multiphoton ionization technique (MPI) depends upon the absorption of two or more photons by a molecule upon irradiation wi...

We present a practical application of a phenomenological model for physicochemical atomization processes in determining heavy metal content by electrothermal atomic absorption spectrometry. Comparison of the analysis results with the NAHRES-33 (IAEA/AL/079) certificate of composition confirms the feasibility of using the proposed ...

Six hundred and thirty references are cited in this review. The information in the review is divided into 12 major areas: books, reviews, and bibliographies; fundamental studies in flames; developments in instrumentation; measurement techniques and procedure; flame emission spectrometry; flame atomic absorption spectrometry; flame ...

High-temperature vaporization of vanadium pentaoxide (V/sub 2/O/sub 5/) samples from vitreous carbon and tantalum furnaces that are heated resistively in ultrahigh vacuum is investigated with the simultaneous atomic absorption/mass spectrometric technique. The advantage of this method is that it allows the observation of intermediates in the vapor phase. The correlated ...

Consideration is given to the influence of flame temperature on the emission signal in atomic emission flame spectrometry and on the absorption signal in atomic absorption flame spectrometry. It is concluded that, if the discussion of the influence of the...

An approach was developed for the preparation of cryogenic ground spiked filter papers with Cu and Zn for use as synthetic calibrating standards for direct solid microanalysis. Solid sampling graphite furnace atomic absorption spectrometry was used to evaluate the microhomogeneity and to check the applicability of the synthetic calibrating standards for ...

A rapid, precise and selective analytical method has been developed for estimation of barium in geological samples by flame atomic-absorption spectrometry. The method consists of precipitation of barium sulphate with ammonium sulphate, followed by dissolution of the sulphates in EDTA at pH 10. The barium in this solution is measured by AAS with a nitrous ...
