The certification of the contents (mass fractions) of Ce, Dy, Er, Eu, Gd, La, Lu, Nd, Pr, Sm, Tb, Tm, Y, Th and U in mussel tissue BCR-668

Funded under: FP5-GROWTH


This report describes the preparation of a mussel tissue (Mytilus edulis) reference material, CRM 668, the homogeneity and stability studies and the analytical work performed for the certification of the contents of rare earth elements (REE) and two additional elements.

The report contains all the results and gives the methods used to certify the contents of 13 rare earth elements: yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), erbium (Er), thulium (Tm), and lutetium (Lu), and of the elements thorium (Th) and uranium (U) (mass fractions expressed as{-1} on a dry matter basis).

Indicative values are given for the content of the REEs holmium (Ho), scandium (Sc) and ytterbium (Yb), and for 8 trace elements: arsenic (As), cadmium (Cd), cobalt (Co), chronium (Cr), caesium (Cs), iron (Fe), molybdenum (Mo) and zinc (Ze). e).
