就定量分析中质量控制的技术重点进行讨论,特别指出取样及样品制备,设备、环境的控制及溯源性的把握等过程的重点技术要求和容易忽略的环节,对试剂的使用及配制,分析结果置信区间的计算和判断等一些细节给予明确要求;综合分析了定量分析过程中不确定度评定方法及要点;介绍了空白分析、重复检测、比对、加标和质控样品分析等常用的质量控制方法及要求,为定量分析工作的有效开展、减少不必要差错提供帮助。
In the quantitative analysis of the quality control of the technical focus of the discussion, in particular, pointed out the sampling and sample preparation, equipment, environmental control and traceability of the process of key technical requirements and easy to ignore the link, the use of reagents and preparation, analysis results Some specifics such as the calculation and judgment of confidence intervals are given. The method and key points for evaluating the uncertainty in the process of quantitative analysis are comprehensively analyzed. Commonly used qualities such as blank analysis, repeated detection, comparison, spike analysis and quality control sample analysis are introduced Control methods and requirements for the quantitative analysis of the effective work to reduce unnecessary errors to provide help.
