摘要
介绍了1∶5万地球化学普查中土壤及水系沉积物样品的分析配套方案、方法检出限以及准确度、精密度;对分析方法的质量控制,包括准确度和精密度的控制、报出率的控制、平行样和异常点样品的重复性检验,对分析流程的质量评估.此方法已应用于大规模土壤及水系沉积物样品的分析测试,提供了巨量的基础数据,取得了良好的应用效果.
This paper introduces the analytical scheme for soil and stream sediment samples from1 ∶50 000 geochemical survey, with the lowest detection limit for methods and controlling values of accuracy and precision. The quality control of chemical analysis includes the control range of accuracy and precision, control of detected rate, repeatability examine of parallel and abnormal samples, and the final quality evaluation for analysis process. With this method, a great number of soil and stream sediment samples in the mapping area were analyzed, which provided a large number of basic data with good application effect.
