| 摘 要： | 介绍一种适用于番茄、黄瓜样品中多菌灵残留量测定的液相色谱质谱联用分析方法。与传统方法相比,本方法具有灵敏度高、结果可靠性高、操作简便等特点。样本以丙酮提取,经过滤,加氯化钠振摇分层,取上清液,注射进入高效液相色谱–质谱–质谱联用仪进行测定。结果表明,样品添加回收率在92.6%～118.5%之间,相对标准偏差为4.20%～10.32%,方法的检测限为0.05mg/kg,符合农药残留分析要求。

| Abstract: | A HPLC- MS- MS technique was developed for determining residue of carbendazim in tomato and cucumber. Compared with traditional methods, this method has high sensitivity, simplicity and reliability. The sample was extracted by acetone. The residues were determined by HPLC - MS - MS. The results showed that the recoveries of carbendazim in tomato and cucumber were from 92.6% to 118.5%. The RSD of the method were from 4.20% to 10.32%. The limit of determination of this method was 0.05 mg/kg which met the requirements of pesticide residue analysis. |
