建立液质联用法测定水产品中泰乐霉素残留量的不确定度评估数学模型,得出了影响不确定度的因素,并对各个不确定度分量进行分析,最后得出利用液质联用法测定水产品中泰乐霉素残留量的不确定度报告。通过分析各个不确定度分量结果,确定该测定过程中的不确定度主要来源于样品提取过程及仪器校准引入的不确定度。 Establish the mathematic model to evaluate the uncertainty of the determination of tylosin in aquatic products, and get the factors that affect the uncertainty, and analyze the components of each uncertainty, and finally come to the conclusion that the use of LC / MS Uncertainty of determination of tylosin residues in aquatic products by usage. By analyzing the results of each component of uncertainty, it is determined that the uncertainty in the determination process mainly comes from the sample extraction process and the uncertainty introduced by the instrument calibration.
