摘要
简要论述了微量金、银矿石系列标准物质的采集、逐级粉碎、过筛、混匀、分装和测试的全过程。用数理统计的方法处理分析数据。采用组间的算术平均值为本标准样品的标准值。样品经颠震试验 ,结果未发生偏析现象。 18年后 ,测试结果与原结果吻合。本标准物质均匀、稳定。标准值准确可靠 ,可供地质、矿山、商检等部门的分析实验室验证微量金。
The paper concisely discussed the total process of the Preparation of series of certified reference materials of micro gold and silver ores,including collecting,crushing progressively,screening,blending evenly,bottling and analyzing.The arithmetical average value of each group was selected and recommended to the certified value of the certified reference materials.A Jolt test was also made.No gravitation segregation was discovered for the sample.Analyses were replicated eighteen years later and results were in accordence with original ones.The certified reference materials are homogeneous and stable,their certified data are accurate and reliable.They provide standards for analytical laboratories in departments of geology,mines,commodity inspection etc,besides,they can examine the analytical methods of micro gold and silver ores and calibrate analytical instruments.
