液相色谱-质谱联用对复杂食品基质中407种多农药残留量的测定

A new method was developed for determination of 407 pesticide residues in complex matrix by using LC-MS with triple quadrupole(QQQ).Comparing with regular method,the method has high sensitivity and repeativity,and was applied for the determination of peticide in real sample with satisfactory results.

食品基质中403种农药残留的测定

复杂食品基质（如谷物、蜂蜜、苹果、肉类）中痕量农残的分离检测非常复杂，本文建立了使用Agilent快速高分离度液相色谱（RRLC）与三重串联四级杆质谱（QQQ）联用的方法，实验得到了良好的线性关系和重复性。与常规HPLC相比。显著改善了复杂样品的分离度，极大地提高了检测灵敏度和分析通量，在复杂食品基质中痕量组分中有着广阔的应用前景。
