在毛细管色谱涂渍技术中,柱尾的封口方法一直是静态法涂渍毛细管技术中的重要问题。因为封口直接影响柱子质量,因此人们十分重视,曾作了不少研究来改进封口方法。从1968年到1982年各种有关色谱杂志都有文章介绍毛细管柱的封口问题,先后有用水玻璃、有机胶、金属塞及各种蜡封口的报道。近年来也有人直接用氢火焰灼烧弹 In the capillary chromatography technique, the sealing method of the column tail has been an important issue in the static coating capillary technology. Because the sealing has a direct impact on the quality of the column, people attach great importance to it and have done a lot of research to improve the sealing method. From 1968 to 1982, a variety of chromatography magazines all have articles on the sealing of capillary columns. There have been reports of water glass, organic glue, metal plugs and various wax seals. In recent years, some people use hydrogen flame to burn the bomb directly
