1)交叉超磁场下毛细管电泳的研究将螺旋状毛细管插入超强永磁体的差距中。当电场施加到该毛细管时，发现电流显示出比没有磁场时更小的值。对氨基水杨酸、对氨基苯甲酸、1，8-蒽醌二磺酸等难分离的位置异构体在磁场作用下得到了较好的分离。2）毛细管电泳分离过程的视频监控利用自行研制的色谱-视频显示器成功地对毛细管电泳分离过程进行了监控。根据迁移距离的不同，条带的前侧呈上升趋势，后侧呈拖尾趋势。通过对毛细管电泳分离过程的多方面研究，提出了新的应用和改进方法。3）毛细管电泳的新方法（1）毛细管电泳的新方法 关于我们 毛细管电泳法测定水样中溶解氧首次用毛细管电泳法测定了水样中的溶解氧。该方法可在5 min内完成各次分析，并可测定低至50 ppb的溶解氧，已成功地应用于河水的分析。(2)β-环糊精毛细管电泳法测定食品添加剂染料的改进发现β-环糊精包合到溶剂中用于分离改善了重现性和峰形。利用这一优势，成功地分离了7种食用染料。结果表明，该方法简便、快速。(3)非水相毛细管电泳（NACE）系统的建立与水相毛细管电泳相比，非水相毛细管电泳具有重现性好、适用范围广等优点。我们讨论了这些新开发的CE方法在每个出版物的未来潜力。少

1) Development of Capillary Electrophoresis under Crossed Super Magnetic FieldA coiled capillary was inserted into the gap of a super-strong permanent magnet. When the electric field was applied to this capillary, it was found that the current showed less value than that without magnetic field. The positional isomers, i.e.p-aminosalicylic acid, p-aminobenzoic acid, 1,8-antheaquinon disulfonic acid, which were hard to resolve, were separated under the magnet with much higher resolution. Similar effect can be obtained even with lowering of temperature of capillary.2) Video Monitoring of Separating Process for Capillary ElectrophoresisSeparating process was successful monitored by our developed chromato-videoscope. The band shows rise up for the leading side of band but shows tailing for the rear side according to the migration distance. With evidences of many aspects of separating process, new applications and improvements were innovated.3) New Methods for Capillary Electrophoresis(1) De … More termination of Dissolved Oxygen in Water Samples Using Capillary ElectrophoresisDissolved oxygen in water samples was analyzed by CE for the first time. Each analysis was performed within 5 min and as low as 50ppb dissolved oxygen can be determined by this method and this method was successfully applied to the analysis of river water.(2) Improvement in the Determination of Food Additive Dye stuffs by Capillary Electrophoresis using B-Cyclodextrin. It was found that the inclusion of B-cyclodextrin into solvent for separation improves the reproducibility and peak shape. Taking this advantage, seven food dye stuffs were successfully separated. It was shown that this method is simple and rapid.(3) Development of Non-aqueous Capillary Electrophoresis (NACE) SystemIn contrast to the usual aqueous phase CE,we charanged to develop the method of non-aqueous CE.The NACE has many advantages in the reproducibility and applicability to various kinds of organic solutes. We discussed the future potentials of these newly developed CE methods in each publication. Less
