Selection of reference methods for the determination of selenium in biological materials

Heydorn, K.; Griepink, B.

Fresenius Journal of Analytical Chemistry — 1990, Volume 338, Issue 3, pp. 287-292

Over the period 1985–1989 the European Community Bureau of Reference (BCR) has certified 7 biological reference materials for selenium with concentrations ranging from 0.03 to 10 mg/kg. Certification analyses were carried out by the most experienced laboratories in the Member States, using Fluorimetry, Hydride formation, combined with ICP or AAS, Electrothermal AAS with or without Zeeman-background correction, Instrumental or radiochemical NAA. Results from these exercises are available in a form suitable for estimating the experimental precision of the various methods as a function of conc...
