| 摘 要： | 本实验旨在建立以改良的QuEChERS作为前处理技术,结合高效液相色谱-串联质谱技术(HPLC-MS/MS)检测饲料中7种镇静剂的检测方法。样品加入乙腈提取,提取液经增强型基质去脂吸附剂(EMR-Lipid)脱脂,盐析后经PSA和C18吸附剂进一步净化浓缩,然后用高效液相色谱-串联质谱方法检测分析。结果表明:7种镇静剂为1~100μg/L时线性关系良好,相关系数均大于0.99,检出限为1.1~2.8μg/kg,定量限为3.7~9.3μg/kg。分别对配合饲料、浓缩饲料和预混合饲料进行3个水平的加标回收实验,平均回收率为84.7%~96.5%,相对标准偏差为3.2%~10.8%。该方法前处理方法快速、简便、灵敏度高,适用于饲料中多种残留镇静剂的同时测定。
