A simple and rapid method for the determination of pirimiphos methyl (O-[2-(diethylamino)-6-methyl-4-pyrimidinyl] O,O-dimethyl phosphorothioate) in formulations by high performance liquid chromatography is described. The sample is dissolved in methanol, and biphenyl is added as an internal standard. Then the sample is chromatographed by reverse phase chromatography on a Zipax octadecylsilane column. A 4 mul injection containing 0.01% pirimiphos methyl produces a 50% full scale peak at the maximum absorbance at 254 nm.
本文描述了一种通过高效液相色谱法测定制剂中甲基嘧啶磷（O-[2-(二乙氨基)-6-甲基-4-嘧啶基] O,O-二甲基硫代磷酸酯）的简单快速方法。将样品溶于甲醇中，并加入联苯作为内标。然后将样品在Zipax十八烷基硅烷柱上进行反相色谱分析。进样4微升含0.01%甲基嘧啶磷的样品，在254nm最大吸收波长处产生一个满量程50%的峰。
