晶体乐果系有机磷杀虫剂，热稳定性差，气相色谱法的重现性差，不稳定。薄层－溴化法操作繁琐。本文介绍的高效液相色谱法具有快速、准确的特点。１ 试验部分１．１方法提要 试样用乙腈溶解，以乙腈＋水（磷酸调ｐＨ＝３．０）为流动相，使用以Ｓｈｉｍ－ｐａｃｋｖｐ－ＯＤＳ?
Crystal dimethoate organophosphate insecticide, poor thermal stability, reproducibility of gas chromatography is poor, unstable. Thin layer - Bromine operation cumbersome. The high performance liquid chromatography described in this article is fast and accurate. 1 Experimental Section 1.1 Method summary The sample was dissolved in acetonitrile, acetonitrile + water (pH adjusted to pH = 3.0) as the mobile phase, using Shim-packvp-ODS?
