中文摘要:
      目的 为提高金属包装罐双酚S迁移量测定的实验过程管理和报告评估水平,建立双酚S迁移量测量的不确定度评定方法。方法 采用高效液相色谱-串联质谱法检测双酚S在体积分数为4%乙酸食品模拟物中的迁移量,结合JJF 1059.1—2012《测量不确定度评定与表示》规定的方法和步骤,建立不确定度评定的数学模型。根据测量模型,分析影响测量不确定度的主要输入量,对各不确定度分量的数值进行计算,对测量结果进行评估。结果 实验中金属包装罐双酚S迁移量测量不确定度报告结果为(2.25±0.302)mg/g,k=2。结论 不确定度评估分析表明,检测仪器分量、校准曲线拟合分量和标准溶液分量是最主要影响因素。
英文摘要:
      The work aims to establish the uncertainty evaluation method for the determination of bisphenol S migration, so as to improve the experimental process management and reporting level of bisphenol S migration determination in can linings. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to detect the migration of bisphenol S in 4% acetic acid food simulants. According to the methods and steps in JJF 1059.1—2012 ''Evaluation and Representation of Determination Uncertainty'', the model for assessing the uncertainty was established. Based on the model, the main input variables affecting the determination uncertainty were analyzed to calculate the uncertainty components and evaluate the determination results. In this experiment, the determination uncertainty of bisphenol S migration in can linings was (2.25±0.302)mg/g, k=2. Uncertainty evaluation and analysis show that in this experiment, the measuring instrument component, calibration curve fitting component and standard solution component are the most important influencing factors.
