| 中文摘要: |
| 利用超高效液相色谱-串联质谱法测定菜籽油中乙基麦芽酚的残留量，并根据建立的数学模型评定该方法的不确定度的各分量。结果表明，标准曲线拟合和标准溶液配制所产生的不确定度分量最大。当菜籽油中乙基麦芽酚含量为10.096 μg/kg时，其扩展不确定度为1.544 μg/kg（k=2）。 |
| 英文摘要: |
| The mathematical model for ethyl maltol residues in rapeseed oil by ultra performance liquid chromatography-tandem mass spectrometry was established and it was used to evaluate the uncertainty components. The results showed that the main sources of uncertainty arose from the standard curve fitting and preparation of standard solution. The expanded uncertainty was 1.544 μg/kg for ethyl maltol contents of 10.096 μg/kg in rapeseed oil (k=2). |
