【摘要】 采用气相色谱法和高效液相色谱法两种方法分别对克菌丹和灭菌丹进行定性定量分析。气相色谱法均以邻苯二甲酸二戊酯为内标物,色谱柱采用3%OV-101 chromosorb AW DMCS 150~177μm,1 m×3 mm玻璃柱,柱温为195℃,汽化温和检测温均为230℃,克菌丹和灭菌丹的回收率分别为99.2%~100.7%和98.8%~99.9%;方法相对标准偏差分别为0.46%和0.59%。高效液相色谱法中使用Nova-PaK C18250 mm×4.6 mm色谱柱,以V(甲醇)∶V(水)=85∶15为流动相,检测波长为225 nm。克菌丹和灭菌丹的回收率分别为99.5%~100.6%和98.9%~99.7%;方法相对标准偏差分别为0.68%和0.51%。更多还原

【Abstract】 The quantitative analysis of captan and folpet by GC and HPLC was studied.Gas chromatography was performed on a 3%OV-101 Chromosorb AW DMCS（150～177 μm） glass column（1 m×3 mm） at a column temperature of 195 ℃ and a detector temperature of 230 ℃ with diamyl phthalate as an internal standard.Recoveries of this method were 99.2～100.7% for captan and 98.8～99.9% for folpet,and variation coefficient was 0.46% and 0.59%,respectively.HPLC was canied out on a Nova-pak C₁₈ column（250 mm×4.6 mm） with V_methanol∶V_water=（85∶15） as mobile phase at a detector wavelength of 225 nm.Recoveries were 99.5～100.6% for captan and 98.9～99.7% for folpet,and variation coefficient was 0.68% and 0.51%,respectively.更多还原
