Optimization of the determination of selenium by atomic-absorption spectrometry: Comparison of two hydride generation systems.
Two commercially available systems for the determination of selenium by hydride-generation and atomic-absorption spectrometry were compared. Chemical and physical parameters were optimized both for an electrothermally heated closed atom-cell method and a flame-heated open-cell technique. Both systems were evaluated with respect to performance and applicability to determination of traces of selenium.
