高效液相色谱法测定水产品中喹乙醇的不确定度评定

Evaluation of uncertainty for the determination of olaquindox in fishery products by HPLC

评定高效液相色谱法测定水产品中喹乙醇的不确定度。依据JJF 1059.1—2012《测量不确定度评定与表示》和SC/T 3019—2004《水产品中喹乙醇残留量的测定液相色谱法》,建立评定喹乙醇不确定度的数学模型,分析其不确定度来源,量化不确定度分量,计算合成标准不确定度与扩展不确定度。当样品中喹乙醇的含量为0.080mg/kg时,扩展不确定度为0.002 mg/kg(k=2)。样品溶液质量浓度引入的不确定度为主要来源。

The uncertainty for the determination of olaquindox in fishery products by HPLC was evaluated.According JJF 1059.1-2012 Measurement Uncertain Evaluation and Expression and SC/T 3019-2004 Determination of Olaquindox Residues in Fishery Products High Performance of Liquid Chromatography,the model for assessing the uncertainty of olaquindox was established,the source of uncertainty was analized,the uncertainty component was quantified,synthetic standard uncertainty and extended uncertainty were calculated.When the content of olaquindox in sample was 0.080 mg/kg,the extended uncertainty was 0.002 mg/kg(k=2).The uncertainty introduced by the mass concentration of sample solution is the main source.
