摘要: |
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。 |

Uncertainty Evaluation of β-Agonists in Pork Liver by Ultra Performance Liquid Chromatography-tandem Mass Spectrometry |

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