采用 Ｏ Ｄ Ｓ２ Ｃ１８ 色谱柱，反相高效液相色谱法，在只改变检测波长而其它色谱条件不变的情况下，完成福美双混剂中福美双、稻瘟灵和甲霜灵３ 个农药组分含量的测定。结果表明，该方法测定３ 个农药组分的准确度分别为９９８ ％ 、９９５ ％ 、９９２ ％ ，精密度分别为０５１ ％ 、２７４ ％ 、２６９ ％ 。 Using O D S2 C18 column, reversed-phase high-performance liquid chromatography, changing only the detection wavelength and other chromatographic conditions unchanged, the United States and the United States to complete the Shuangmei Shumei Shuangmei, rice blast and metalaxyl three pesticides Determination of component content. The results showed that the accuracy of the method for the determination of three pesticide components were 998%, 995% and 992%, respectively, with the precision of 051%, 274% and 269%, respectively.
