热带水果中硒形态分析的不确定度研究

Uncertainty Evaluation of Selenium in Tropical Fruit by AFS Method

通过创建数学模型并选择评估的方法,分析了原子荧光光度法测定热带水果中硒不确定度的主要来源,对分析过程中的样品称量、消解、定容体积、标准配制、曲线拟合、重复性等6个不确定分量进行分析和合成,计算出硒的扩展不确定度,为系统分析检测结果的准确程度和方法的可靠性研究提供参考。

Analysis of the AFS method for determination of Se in the process of measurement uncertainty and the main source,through the creation of mathematical models and choose assessment method,the process of digestion of the samples weighing,digestion,the volume size,determination of the standard process of preparation,curve fitting,equipment measurement repeatability six components of uncertainty anal ysis and synthesis,and calculate the expanded uncertainty.
