An approach to the practical implementation of the standard method of the direct determination of phosphorus in vegetable oils by electrothermal atomic absorption spectrometry with automated sample injection was proposed. ...

Shadow spectral filming is used to study the spatiotemporal dynamics of the formation and dissipation of vapors of potassium sulfate and aluminum and indium nitrates in a transversely heated graphite furnace atomizer. The ...

We have investigated the influence of the sodium chloride and potassium sulfate excess in a sample on the absorption signals of Ag, Al, Au, As, Bi, Cd, Cu, Ga, Ge, In, Mn, Pb, Sb, Se, Sn, and Tl in a transversely heated ...

An alternative method is developed for recording atomic absorption with spatial resolution on the basis of a position-sensitive photodetector. The main requirements on the optical system, the source, the radiation detector, ...

This paper describes an experimental apparatus for studying the dynamics of the variation of the spatial distribution of the absorbing layers in a two-stage atomizer. An optical system with a telecentric beam, using a diode ...

This paper analyzes the factors that ensure that optical atomic-absorption spectrophotometers can give reliable information on the composition of a sample introduced into the atomization zone. It discusses how the parameters ...

A two-stage atomizer for atomic absorption spectrometry is proposed. Its distinctive feature is the introduction of an extra stage of the fractional condensation of analyte atoms and the carrying out of the analytical cycle ...
