福美双混剂HPLC分析方法的研究

Study on Analysis Method of Mixing Thiram Agent by HPLC

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 ％ 。

The contents of thiram, metalaxyl and isoprothiolane in mixing thiram agent were determined by HPLC and ODS 2 C 18 chromatogram columniation under changing examine wavelength only. The results showed that the accuracy of thiram, metalaxyl and isoprothiolane was 99.8%, 99.5%, and 99.2%, and the precision was 0.51%, 2.74% and 2.69%, respectively.
