英文摘要	Two Co-rich seamount crust reference materials, MCPt-1 and MCPt-2, were prepared using ultra-fine particle size milling technique and characterised for the platinum-group elements (PGEs). The raw material for these two reference materials was collected separately from the Magellan seamounts of the western Pacific Ocean and the seamounts of the central Pacific Ocean by Russian and Chinese scientists. First, they were ground by ball mill to a -200 mesh powder, then further processed by ultra-fine jet mill and well-mixed. The particle size distributions of the samples were tested by a laser particle analyser; the average particle size was 1.8 and 1.5 mu m (equal to about 2000 mesh) respectively. The homogeneity of six major and minor elements in these two materials was tested at the milligram level of sampling mass by high-precision wavelength dispersive X-ray fluorescence (XRF) spectrometry and at the microgram level of sampling mass by electron probe microanalyser. The homogeneity of more than forty trace elements, including Pt, was tested at the microgram level of sampling mass by LA-ICP-MS. Except for Rh, all PGEs were determined by isotope dilution-ICP-MS. Platinum in MCPt-1 and MCPt-2 was characterised as certified values, whereas the other five PGEs in MCPt-1 and MCPt-2 were reported as reference values. In addition, the information values of sixty-two major, minor and trace elements were obtained by XRF, ICP-AES and ICP-MS. The minimum sampling mass for the determination of PGEs was 1 g, while the minimum sampling mass for the determination of the other elements was 2-5 mg.
