-
摘要: 分析了区域地球化学调查样品分析中原有的质量控制方法的不足,提出了采用实验室内部自我质量控制和实验室外部质量控制相结合的方法。对实验室外部质量控制方法进行了试验,并将测试数据绘制的元素虚拟地球化学图进行相似性比较,以求改进和完善区域地球化学调查样品分析质量控制方法,促进分析测试质量进一步提高。Abstract: In this paper, the defects of the old quality control method for the analysis of samples in regional geochemical survey are discussed and a new quality control method, which is based on the laboratory internal quality control and the external quality cont
