采用超高效液相色谱－串联质谱法（ UPLC－MS／MS）测定猪肝中9种β－受体激动剂残留量，对标准溶液、标准曲线、样品称量、称量重复性、定容体积等因素进行分析，通过评定各不确定度分量及标准不确定度，得出9种β－受体激动剂的合成相对标准不确定度为5．60％～8．90％，影响较大的因素为标准曲线和测量重复性。

Evaluation on uncertainty of measurement in the determination of 9 kinds ofβ-agonists in pork liver by ultra performance liquid chromatography-tandem mass spectrometry was practiced. The main factors, including standard solution, standard curve, weighing of sample, measurement repeatability, and volume were evaluated. The combined uncertainty of 9 kinds ofβ-agonists was in the range of 5.60%~8.90%. The results showed that the measurement uncertainty was mainly due to the standard curve and measurement repeatability.
