Certification of the mass fractions of As, B, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn and Zn in rye grass - Certified Reference Material ERM®-CD281

Abstract

This report describes the preparation and certification of the rye grass Certified Reference Material (CRM) ERM-CD281. This CRM replaces the exhausted predecessor BCR-281. ERM-CD281 was processed and certified by the European Commission, Directorate General Joint Research Centre, Institute for Reference Materials and Measurements (IRMM), Geel, Belgium. Certification of the CRM included testing of the homogeneity and stability of the material as well as the characterisation using an intercomparison approach. ERM-CD281 has been certified for its content of As, B, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn and Zn. The main purpose of the material is to assess method performance, i.e. for checking accuracy of analytical results. As any reference material, it can also be used for control charts or validation studies.
