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2 a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. Reported three seamounts cobalt and cobalt crusts developed in China and Russia developed the standard material GSMC-1, 2, 3. The three reference materials were taken from the Western Pacific Magellan seamounts and the Central Pacific seamounts samples were air-dried, matching , Ball milling prepared into a uniform powder sample, the uniformity of the use of high-precision X-ray fluorescence spectrometry samples of chemical components using multi-laboratory collaborative analysis at home and abroad set value, with eight domestic laboratories and eight A foreign laboratory participated in the cooperative analysis of the test components were 57, of which GSMC-1,2 has 43 components as a guaranteed value, 10 components as a reference value; GSMC-3 has 45 components To ensure the value of eight components as a reference value after more than 2 a trial, three standard substances in 2005 by the national metrology department approved as a national standard material, its number GBW07337, GBW07338 and GBW07339.
