This article describes the use of two definitive methods for the determination of Se and As traces in biological materials intended for proficiency testing. Radiochemical neutron activation analysis (RNAA) definitive methods are based on reactor neutron activation with a very selective and quantitative post-irradiation separation of the indicator radionuclide by column chromatography, followed by γ-ray spectrometric measurement. Each of these methods has detection limit of the order of ng·g–1 or better, and yields accurate results. The expanded standard uncertainty for both methods is ca. 4%. Definitive RNAA methods were used for establishing assigned values for Se and As in materials employed in proficiency testing of “Plants” series.
