Determination of lead in whole blood by electrothermal atomic-absorption spectrometry using graphite probe atomisation

Abstract

Atomisation from a pyrolytic graphite probe, placed in a hot and constant-temperature HGA 70 furnace, was used for the direct determination of lead in diluted whole blood. Substantial reductions in the classical vapour-phase interference effects by up to 2%m/V magnesium chloride and calcium chloride and 1.5%m/V sodium chloride allowed the use of aqueous standard solutions for analytical calibration. Good agreement with national (UK) mean values was obtained for the analysis of quality control blood samples. The analytical precision is equivalent to that with conventional atomisation, but with improved sensitivity.
