A procedure for the determination of vanadium in an inorganic matrix,such as may result from the decomposition of biological samples, isdescribed. The method utilizes purely instrumental thermal-neutron activationanalysis preceded by separation of vanadium from interfering elements byextraction with 8- hydroxyquinoline. Samples of human blood serum were analysed by the aid of dry-ashing as well as wet-ashing techniques. Dry ashing in porcelain crucibles introduced significant amounts of vanadium into the samples, and subsequent analysis of the porcelain glaze showed a vanadium content of ∼ 2 ng/cm. Analytical results from samples ashed in quartz crucibles or by wet ashing showed a mean value of 0. 0046 ± 0.0008 microgram of vanadium per millilitre of human blood serum. <br/
