Abstract
A detailed study of interfering processes in the determination of As, Sb and Se using a twin-channel hydride generation flow-system is prese nted. The influence of As, Sb, Se and Sn on all three studied elements has a similar character and occurs in the gas phase only. In the pres ence of bismuth and tellurium interferences occur also in the liquid p hase. It was found that arsenic and antimony may influence the analyti cal signals of elements with analytical lines in the range from 190 to 235 nm by non-specific absorption due to molecular band spectra.
