摘要: 我国开展区域地球化学调查工作以来,全国地质实验室在样品分析时对质量的控制都相当重视,除了按照相应规范进行了内部和外部质量监控外,还各自采取了一些其他措施来提高区域地球化学样品分析质量,管理办法的完善使得区域地球化学样品分析技术水平和质量较以前有了较大的提高,高质量的分析数据取得了较好的元素成图效果。从新疆哈拉奇地区地球化学调查样品测试特点出发,针对本实验室实际和各大型仪器检出限的不同,选定了区域地球化学调查样品元素的分析方法配套方案。并且对检测数据的质量监控过程进行总结,对质量监控的目的和方式,提出一些认识和意见,为化探样品分析测试质量评价提供了一种简便快捷、科学合理的质量评价方法。Abstract: Since the beginning of regional geochemical survey carried out in China, national geological laboratories have paid considerable attention to the quality control for sample analysis. Except for internal and external quality control in accordance with the criteria, a number of other measures were respectively taken to improve sample analysis quality. By perfecting the regulation method, technical level and quality of sample analysis have been greatly improved. High-quality analysis data has led to better element mapping results. Considering the characteristic of regional geochemistry sample determination of Halaqi, Xingjiang and the different detection limits of instruments in the laboratory, this article selected the matching plan of regional geochemistry sample element analysis methods. The quality monitoring process of test data is summarized. Some understandings and suggestions were raised about quality control objective and approach, which provides a simple and efficient, scientific and reasonable quality evaluation method for geochemical analysis of samples.
