摘要:
为更好地指导果蔬残留检测工作，利用气相色谱（附火焰光度检测器FPD）和三重四级杆串联质谱同时对油麦菜基质和苹果基质中的甲拌磷及其代谢物甲拌磷砜和甲拌磷亚砜进行检测。结果表明：与气相色谱相比，尽管三重四级杆串联质谱检测后样品具有更明显的基质效应，但是通过利用基质标扣除大部分基质效应后，却可以得到更好的回收率，范围在85.9%~105.0%，特别是在检测的农药含量较低的时候。同时，与气相色谱相比， 三重四级杆串联质谱具有更高的灵敏度，能检测到更低浓度的农药残留，更适用于果蔬中农药残留的痕量分析。
Abstract:
To better guide the residue detection of fruits and vegetables,GC-FPD and GC-MS-MS used to test phorate and phorate sulfone,phorate sulfoxide of lettuce and apple at the same time.The result showed that the sample has a more pronounced matrix effect when tested by GC-MS-MS compared with GC.However,a better recovery rate could be achieved by deducting most of the matrix effects using the matrix marker after testing by GC-MS-MS，the recovery range was 85.9%~105.0%，especially at low levels of pesticides tested.Meanwhile,compared with gas chromatography,GC-MS-MS has higher sensitivity，and able to detect lower concentrations of pesticide residues,which is more suitable for trace analysis of pesticide residues in fruits and vegetables.
