PREPARATION OF THE BOVINE KIDNEY AND BOVINE MUSCLE REFERENCE MATERIALS AND THE CERTIFICATION OF ELEMENT CONTENTS FROM INTERLABORATORY COMPARISONS

Results obtained in interlaboratory comparisons on candidate reference materials Bovine Kidney and Bovine Muscle, in which more than 32 labo ratories participated employing atomic spectrometry, electrochemical, and nuclear analytical techniques, have been evaluated using combined statistical and analytical considerations. Certified and/or informatio n values for the elements Br, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, ME, Mn, M o, Na, P, Pb, Rb, Se, and Zn have been established. Information on con tents of the elements Al, As, Au, Cs, Li, Ni, Sb, Sn, Sr, and V is als o presented.
