Certification of 22 elements in a pure copper (99.5%) sample for spark emission and X-ray fluorescence spectrometry (CRM BAM-376)

Abstract

 The element contents of Ag, Al, As, Be, Bi, Cd, Co, Cr, Fe, Mg, Mn, Ni, P, Pb, S, Sb, Se, Sn, Te, Ti, Zn and Zr in a pure copper (99.5%) sample (CRM BAM-376) for use in spark emission and X-ray fluorescence spectrometry were certified and the certified values are given. For Si, the certification has not yet been completed, the content of this element will be certified later. The sample was produced and certified in collaboration with the Committee of Chemists of the GDMB Gesellschaft für Bergbau, Metallurgie, Rohstoff- und Umwelttechnik. Data of the homogeneity testing and the certification campaign with 14 participating laboratories using different analytical methods are reported.
