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

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