摘要
以采用文献方法合成的化合物羧基丁二酰爷环糊精微球为固定相,通过溶胶-凝胶技术制备了毛细管气相色谱柱。用此毛细管柱分离了难以分开的2种氨基酸和3种手性药物对映体。对此分离柱的色谱参数进行了测定,5对对映体的分离因子在1.22~3.21之间,分离度在7.05~22.74之间。分离DL-甲硫氨酸的试验中,测得其分离因子的相对标准偏差(n=7)小于0.65%。所有数据表明,该色谱柱分离效果良好,适宜用于气相色谱分析。
A capillary chromatographic column was prepared by using carboxysuccinyl-β-cyclodextrin microspheres as stationary phase and applying the sol-gel technique. This novel column was used in the separation of 2 amino acids and enantiomers of 3 chiral drugs which were very hard to separate. Several main parameters of this chromatographic column were determined and the following results were obtained: (1) values of separation factor for 5 pairs of enantiomers were found in the range of 1.22-3. 21, with resolution in the range of 7.05-22. 74; (2) relative standard deviation (n=7) of separation factor (β) of DL-methionine was found to be less than 0. 65%. As a whole, this new column showed high efficiency in separation and was favorable to be used in GC analysis.
