摘　　要：目的:利用GC-MS法测定蜂蜜中双甲脒残留量并进行不确定度评定。方法:运用气相色谱-质谱法对蜂蜜中双甲脒残留量进行测定,通过建立数学模型,分析各不确定度来源,对不确定度分量进行评定。结果:双甲脒残留量的不确定度主要由标准溶液的配制过程及样品前处理过程引入。当双甲脒残留量为0.122 4 mg·kg^(-1)时,扩展不确定度为0.008 9 mg·kg^(-1)(k=2)。结论:该方法适用于蜂蜜中双甲脒残留量的不确定度分析,为检验检测数据提供科学可靠的依据。Objective:To evaluate the uncertainty of determination of diformamidine residue in honey by GC-MS.Method:The residual quantity of diformamidine in honey was determined by gas chromatographymass spectrometry.The source of uncertainty was analyzed and the component of uncertainty was evaluated by establishing mathematical model.Result:The uncertainty of dimethylcarbamazine residue was mainly introduced by the preparation process of standard solution and the pretreatment process of samples.When the residual amount of diformamidine is 0.1224 mg·kg^(-1),the extended uncertainty is 0.0089 mg·kg^(-1)(k=2).Conclusion:The method is suitable for the uncertainty analysis of diformamidine residue in honey,and provides a scientific and reliable basis for testing data.
