| The Collaborative Study on Geochemical Reference Materials of Pacific Polymetallic Nodules and Sediments |
| The collaborative study on the geochemical reference materials of two polymetallic nodules(GSPN_2 and GSPN_3) and two marine sediments(GSMS_2 and GSMS_3) has been completed. The raw materials of GSPN_2, GSPN_3, GSMS_2 and GSMS_3 were collected from the Pacific CC(clarion_clipperton) zone and the central_Pacific basin(CP zone) respectively. The selected materials were processed to be homogeneous powder(size<74μm). The homogeneity of prepared samples was tested by X_Ray Fluorescence(XRF) method. For all tested elements of 30 subsamples taken in random from a batch, their measurement precision(Relative Standard Divetion, RSD) is better than 0.6%. 32 laboratories, including 18 abroad laboratories participated in the collaborative analysis of the four samples. 79(in GSPN_2 and GSPN-3) and 81(in GSMS_2 and GSMS-3) constituents were determinated, of which 63 were certified. The sums of the contents of constituents determinated for the four samples are 99.7%, 99.5%, 99.8% and 99.7% respectively. The four reference materials, as Certified Reference Materials(CRMs), had been approved by State Bureau of Technical Suppervision in 1997. The serial numbers are GBW07295, GBW07296, GBW07315 and GBW07316 respectively. |
