Characterization and vapour phase interference studies of a flame heated holed quartz T-tube as atomization cell for hydride generation atomic absorption spectrometry

Abstract

Characterization and mutual hydride forming element interference studies of a flame heated holed quartz T-tube as atomization cell for HGAAS were performed. Characteristic concentrations, limits of detection and linear ranges were determined for As, Bi, Sb and Se. Also, the mutual interferences of these elements were investigated. Extended non-interferent ranges were observed in most of the studied cases and such improvement was obtained at no great expense with regard to sensitivity and detection limits.
