分析数据质量是反映样品加工质量、分析方法质量、试剂与仪器质量、分析人员及管理人员质量的一个综合性信息。除加工以外,分析方法质量是保证分析数据质量的最关键的环节。 分析方法的质量评估 近十年来,有色地质实验室根据全国区域化探扫面计划和要求,在学习国内外先进分析方法的基础上,通过大量的试验研究工作已总结出一套完善的分析方法,建立了多元素定量分析体系,较好的满足了化探样品38个元素分析的检出限要求,为区域化探扫面提供了大量的分析数据。但目前有些分析方法承担大批量的测试任务并不理想,突出反映在报出率、成
Analytical data quality is a comprehensive information that reflects the quality of sample processing, the quality of analytical methods, the quality of reagents and instruments, and the quality of analysts and managers. In addition to processing, the quality of the analytical method is the most critical link to ensure the quality of the analytical data. Quality Assessment of Analytical Methods Over the past decade, the Non-ferrous Geological Laboratory has concluded a set of comprehensive analytical methods based on the national plans and requirements for regional exploration and scanning, based on the study of advanced analytical methods at home and abroad, through a large number of experimental studies. A multi-element quantitative analysis system was established, which satisfies the detection limit requirements of 38 elemental analysis of geochemical exploration samples and provides a large amount of analytical data for regional exploration scans. However, at present, some analysis methods are not ideal for taking large batches of test tasks, but they are mainly reflected in the reported rate and percentage.
