GC-MS法测定果冻中邻苯二甲酸二烯丙酯不确定度的方法
|
摘要
【目的】建立气相色谱-质谱法测定果冻中邻苯二甲酸二烯丙酯含量的不确定度方法,以提高实验结果的准确性。【方法】建立不确定度评定的数学模型,分析检测各步骤不确定度来源、计算评估各不确定度分量并计算扩展不确定度。【结果】当果冻中邻苯二甲酸二烯丙酯含量为0.941 2 mg/kg时,其扩展不确定度为0.051 2 mg/kg(K=2,P=95%)。【结论】本评估模型中,不确定度主要来源于邻苯二甲酸二烯丙酯标准溶液配置、标准曲线拟合及样品处理过程。
[Objective] To establish uncertainty evaluation for the determination of diallyl phthalate in jellies by Gas chromatography-mass spectrometry(GC-MS),thus obtaining accurate results. [Methods] A mathematical model was established and sources of uncertainty during the analysis process that might be introduced were analyzed and quantified.The expanded uncertainty was also calculated. [Results] When the diallyl phthalate content in jellies was 0.941 2 mg/kg,the expanded uncertainty of measurement results was 0.051 2 mg/kg(K=2,P=95%). [Conclusion] In this paper,the main sources of measurement uncertainty are methanol standard solution,standard curve fitting and sample preparation.
