【摘要】 [目的]建立一种高效液相色谱-串联质谱测定溴虫氟苯双酰胺悬浮剂的分析方法。[方法]采用Agilent Zorbax RRHD Eclipse Plus C₁₈色谱柱，流速0.3 mL/min,柱温30℃条件下，以乙腈-水（0.1%甲酸+5 mmol/L乙酸铵）（体积比70∶30）作为流动相，ESI离子源，在多反应监测（MRM）模式下进行正离子扫描，测定样品中溴虫氟苯双酰胺的含量。[结果]方法的线性相关系数为0.9997，标准偏差为0.155，变异系数为1.59%，平均回收率为101.21%。[结论]该方法线性关系良好，准确度和精密度高，符合溴虫氟苯双酰胺悬浮剂中有效成分的定量分析要求。更多还原

【Abstract】 [Aims] A HPLC-MS/MS method for determination of broflanilide SC was established. [Methods] ESI ion source and the positive mode under multiple reaction monitoring（MRM） mode was performed to determine the concentration of broflanilide in the sample. Agilent Zorbax RRHD Eclipse Plus C₁₈ was used at 30 ℃, acetonitrile-0.1%formic acid water+5 mol/L ammonium acetate（70:30, by vol） was used as mobile phase with flow rate of 0.3 mL/min.[Results] The linear correlation coefficient was 0.9997, the standard deviation was 0.155 with the variation coefficient of 1.59% and the average recovery of 101.21%. [Conclusions] The method has a good linear relationship, high sensitivity, which is suitable for quantitative analysis of broflanilide SC.更多还原
