火焰原子吸收光谱法测定白兰地中铜测量不确定度评定

Cu Content in Brandy Measured by Flame Atomic Absorption Spectrometry & Cu Content Uncertainty Evaluation

采用原子吸收光谱法测定白兰地酒中的铜含量,对逐级稀释配制的单元素标准溶液测量过程等进行全面分析,从不确定度来源和量化不确定度分量等方面进行研究,得出测量样品中铜含量的扩展不确定度和相对不确定度。

Flame atomic absorption spectrometry was applied to measure Cu content in brandy. Furthermore, comprehensive analyses including the measurement process of progressive diluted singleton standard solution etc. were done from the angle uncertainty source and quantizing uncertainty component etc. to determine expanding uncertainty and relative uncertainty of Cu content in measured samples.
