Abstract:

The results of an interlaboratory comparison are reported for the lead isotope composition and for trace element concentrations in NIST SRM 1400 Bone Ash obtained using quadrupole and magnetic-sector inductively coupled plasma mass spectrometry (ICP-MS) and (for the Pb isotopes only) thermal ionization mass spectrometry (TIMS). Concentrations of 42 analytes{,} in addition to the 17 listed by NIST{,} are presented{,} including the rare earth elements. Twenty-six of these analytes are considered to have been reliably determined based upon the agreement of two or more laboratories{,} or based upon data from a single laboratory with consideration of the potential interferences. Nickel and cobalt were reliably determined only by medium-resolution magnetic-sector ICP-MS{,} or by quadrupole ICP-MS following matrix separation with an ion-exchange column. The Pb isotope composition reported here from TIMS agrees within 0.09% relative with previously reported{,} non-certified values for this standard reference material. The atomic abundances ofPb{,} Pb and Pb determined by ICP-MS are statistically equivalent to the best-estimate TIMS values or differ statistically by 0.17% at most. The information provided in this paper will enhance the utility of this reference material.
