摘要

摘要: 报道了我国与俄罗斯合作研制的三个海山富钴结壳标准物质GSMC-1,2,3.这三个标准物质的原样分别取自西太平洋麦哲伦海山和中太平洋海山.样品经风干、选配、球磨制备成均匀的粉体样品,其均匀性采用高精度的X-射线荧光光谱法检验.样品的化学组分采用国内外多实验室协同分析方式定值,有八个国内实验室和八个国外实验室参加了合作分析.测试组分均为57个,其中GSMC-1,2有43个组分定为保证值,10个组分作为参考值;GSMC-3有45个组分定为保证值,8个组分作为参考值.经2a多的试用,三个标准物质已于2005年被国家计量部门批准为国家一级标准物质,其编号分别为GBW07337,GBW07338和GBW07339.

Abstract: The collaborative preparation of three seamount cobalt-rich crust reference materials GSM C-1~3 by China and Russia is presented.The samples were sampled from the western and central Pacific seamount zones.After the raw samples were dried in ambient air and crushed,they were ground in a ball mill to form a well-mixed powder.The homogeneity of the samples wastested using X-ray fluo rescence spectrometry(XRF) with high-precision.Eight home laboratories and eight international laboratories participated in the collaborative analysis programme.Fifty-seven elements or constituents were analy sed,and among those,43 were certified in GSM C-1 and 2,and 45 const it uents were certified in GSMC-3.Ten constituents were regarded as information value in GSM C-1 and 2,and eight const ituents were regarded as information value in GSM C-3.These three reference materials have been approved as certified reference materials by the Administ ration of Quality Supervision and Inspection and Quarantine(AQSIQ,China) in 2005,the serial number is GBW07337 for GSM C-1,GBW07338 for GSM C-2 and GBW07339 for GSM C-3.
