对有机磷农药乐果乳油的离子淌度谱行为进行了研究，实验结果表明，质子高亲合能的氨水能较好地提高乐果乳油的检测选择性，当载气中分别加入多种混合溶剂，选择性可以得到进一步提高，其中以氨水和丙酮的混合溶剂选择性最好。
The ion mobility spectroscopy of organophosphorus pesticide dimethoate was studied. The experimental results show that proton high affinity ammonia can improve the detection selectivity of dimethoate. When the carrier gas is mixed with a variety of mixed The selectivity of the solvent can be further improved, of which the selectivity to ammonia and acetone is the best.
