摘要: 目的 建立超高效液相色谱质谱联用(UPLC-MS/MS)法测定大鼠血浆氨溴索的方法,并分析该方法的不确定度。方法 分析测定方法建立过程中不确定度的来源并进行合成。结果 大鼠血浆中氨溴索在低浓度(20 ng·mL-1)和高浓度(400 ng·mL-1)测定时的扩展不确定度分别为1.25、20.82 ng·mL-1P=95%,k=2)。结论 UPLC-MS/MS法测定大鼠血浆中氨溴索浓度的不确定度,在低浓度时主要由标准曲线拟合、溶液配制及重复性引入,高浓度时主要来源于血浆回收率、基质效应。

Abstract: Objective To develop a method for the determination of ambroxol in rat plasma using ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS/MS), and to analyze the uncertainty associated with this method. Methods The sources of uncertainty in the process of establishing the UPLC-MS/MS method for determining ambroxol in rat plasma were analyzed and synthesized. Results The extended uncertainties at a low concentration (20 ng·mL-1) and at a high concentration (400 ng·mL-1) of ambroxol in rat plasma were 1.25 ng·mL-1 and 20.82 ng·mL-1, respectively (P=95%, k=2). Conclusion The uncertainty that arises from the determination of concentrations of ambroxol in rat plasma using the UPLC-MS/MS method is primarily introduced by standard curve fitting, solution preparation, and repeatability at low concentrations, and by the plasma recovery rate and matrix effects at high concentrations.
