| 摘 要： | 采用微波辅助合成技术,快速制备以聚酰胺-胺(poly(amidoamine),PAMAM)树枝状分子为固定相的开管毛细管电色谱柱.与常规合成方法相比,微波辅助合成法可以提高反应速度,极大地缩短制备周期.在pH 5.7～8.0范围内, 随着PAMAM树枝状分子代数的增加,毛细管电渗流(EOF)逐步下降.对丙氨酸和脯氨酸进行分离的实验结果表明,随着PAMAM树枝状分子代数的增加,分离度逐步增大,3代PAMAM树枝状分子修饰的毛细管柱具有良好的分离效果.以丙酮标记物连续测定10 d,柱效下降3.85%, 表明采用微波辅助合成技术制得的PAMAM树枝状分子修饰的毛细管柱具有良好的稳定性.

| Abstract: | Microwave irradiation was introduced into the preparation of poly(amidoamine)(PAMAM) dendrimer modified open-tubular capillary electrochromatographic column.Compared with the conventional method,the preparation procedure was simple and rapid.At the pH range of 5.7-8.0,electroosmosis flow of the obtained columns was decreased gradually with the increase of PAMAM generations.The separation of alanine and proline was demonstrated in the obtained columns.The results showed that the resolution of the two compone... |
