The certification of the mass concentrations of aluminium, selenium and zinc in human serum BCR-637, BCR-638, BCR-639
This report documents the preparation, homogeneity, stability and certification of three liquid human serum materials, i.e. BCR-637, BCR-638 and BCR-639 with certified concentrations of aluminium, selenium and zinc. The homogeneity studies demonstrated that the materials are homogeneous with respect to the content of aluminium, zinc and selenium. The materials were subjected to a certification campaign for which the analytical work is described. Uncertainty contributions for stability, homogeneity and characterisation were included in the combined and expanded uncertainties assigned to the certified values.
