摘要：

Isotope dilution inductively coupled plasma magnetic sector field mass spectrometry (ID-ICP-MS) was applied to the trace analysis of selected elements of Syenite rock-type reference material SARM 2 as part of the continuing work programme on the re-evaluation of certain South African Reference Materials. The results for Ba, Cd, Cu, Me, Ni, Pb, Sr and Zn are compared with the initial certification data for SARM 2, as well as published data for these elements since 1978. Complete uncertainty statements were calculated according to the ISO GUM and EURACHEM/CITAC guidelines for quantification of uncertainty of measurement.
