摘要
首次以溶胶 -凝胶 (Sol-gel)方法制备了 2 ,6 -二丁基β -环糊精 ( β -TB -CD)毛细管电色谱开管柱 .以苯胺 ,苯酚和苯甲酸混合体系对其进行了评价 ,获得的柱效分别为2 837× 1 0 4,4 5 31× 1 0 4,7 6 35× 1 0 4理论塔板数 /m ,保留时间和峰面积的RSD分别为 1 6 4 % ,1 1 5 % ,2 0 7%和 6 0 2 % ,7 45 % ,7 0 2 % .结果令人满意 .
A novel open-tubular capillary electromatography column(OTCEC) coating 2,6-dibutyl-β-cyclodextrin(β-TB-CD)was prepared using Sol-gel method for the first time.The column performance was evaluated with mixture composing of aniline,phenol and benzyl acid.The theory plate number was 2.837×10 4,4.531×10 4and 7.635×10 4/m;RSD% of the migration time was 1.64%,1.15% and 2.07% respectively.
