Comparison of AAS with hydride concentration in a graphite furnace with other spectrometric techniques

The common method for the determination of arsenic and antimony is based on hydride generation, which in turn can be determined by various detection techniques. Preconcentration of the hydrides in a graphite furnace with subsequent atomization and detection in the absorption mode has been compared with direct atomization of the hydrides in the quartz tube as well as with inductively coupled plasma atomization and excitation in the emission mode. Detection limits, possibility of mutual interferences and multielement capability were compared for these techniques. (C) 1997 Elsevier Science B.V.
