【摘要】 采用气相色谱法和液相色谱法2种方法分别对戊唑醇、丙环唑和三唑酮进行定性定量分析,气相色谱法中都以邻苯二甲酸二戊酯为内标物,色谱柱都采用3%OV-101chromosorbAWDMCS150￣177μm1m×3mm玻璃柱,柱温为200～205℃,汽化温度和检测温度均为230℃,戊唑醇、丙环唑和三唑酮的回收率分别为99.1%～100.3%,98.5%～99.8%和99.3%￣100.7%;方法变异系数分别为0.34%,0.51%和0.37%。高效液相色谱法中使用Nova-PaKC18250mm×4.6mm色谱柱,以甲醇+水=85+15为流动相,检测波长为225nm。戊唑醇、丙环唑和三唑酮的回收率分别为99.1%～100.7%,98.9%￣99.6%和99.9%～101.2%;方法变异系数分别为0.74%,0.43%和0.58%。更多还原

【Abstract】 The quantitative analysis of tebuconazole,propiconazole and triadimefon by GC and HPLC were studied.The operation conditions of gas chromatographic method were:3%OV- 101 on Chromosorb AW DMCS,1m×3mm(i.d.)glass column at column temperature of 200～205℃ and detector temperature of 230℃.The internal standard was disoamyl phthalate.The recoveries were 99.1%～100.3%,98.5%～99.8% and 99.3%～100.7%,their coefficients of variation were 0.34%, 0.51% and 0.37% respectively. The operation conditions of HPLC were:C18 column(250mm× 4.6mm), methanol +water =85 +15( V/V) as mobile phase, UV detector at 225 nm.The recoveries of this method were 99.1%～100.7%,98.9%～99.6% and 99.9%～101.2%.The coefficients of variation were 0.74% , 0.43% and 0.58% for tebuconazole, propiconazole and triadimefon respectively.更多还原
