选择了两种难挥发、强极性及热不稳定农药 (三嗪类除草剂——阿特拉津及有机磷类农药——二嗪农 )进行了其碎片谱研究。 6种农药 (阿特拉津、西草净、西玛津、杀草净、涕灭威、绿麦隆 )混合物经过 HPLC良好分离后实现了HPLC/APCI/CIDMS的测定 ,获得了各自的特征碎片谱。采用 CID技术 ,既可得到待测物的分子量 ,又可得到其结构信息。
Two fragile, polar and thermolabile pesticides (triazine herbicide - atrazine and organophosphate pesticides - diazinon) were selected for their fragmentation studies. The HPLC / APCI / CIDMS assays of the six pesticides (atrazine, simethrine, simazine, chlorhexidine, aldicarb, and chlorotoluron) were well separated by HPLC and their individual characteristics were obtained Fragment spectrum. Using CID technology, both the molecular weight of the analyte can be obtained, and its structure can be obtained.
