Abstract
SEEY-1 is a selenium-82 labelled selenium enriched (selenized) yeast Certified Reference Material (CRM) from the National Research Council of Canada (NRC) with information on selenomethionine and total selenium content. A unit of SEEY-1 consists of approximately 5 grams of selenium enriched yeast in an amber glass vial. This material is intended for use as a matrix-matched isotopically-labelled standard for isotope dilution analysis of selenium enriched yeasts. The isotopic composition of selenium in this material is estimated as n(82SeMet)/n(SeMet) = 0.942 mol/mol.
