| 摘 要： | 建立了超高效液相色谱(UPLC)同时测定水产品中氯霉素、呋喃唑酮和甲硝唑3种兽药的分析方法.样品采用乙酸乙酯提取,无水Na2SO4脱水,减压浓缩至干,用甲醇溶解,正己烷脱脂.采用ACQUITYTM UPLC BEH C18色谱柱(100 mm×2.1 mm,1.7 μm),以乙腈-0.004% H3PO4溶液为流动相梯度洗脱,结合波长变化程序,在7.0 min内可完成3种违禁兽药的多残留检测.在0.01～10 mg/L线性范围内,线性相关系数r为0.9997,检出限(LOD)为0.01 mg/L,最低定量限(LOQ)为1.0 μg/kg.空白样品中4个添加水平(1、2、5和10 μg/kg)下,3种违禁兽药的平均回收率为72.3%～119.6%;日内及日间相对标准偏差为2.2%～9.9%.
