毛细管离子分析中迁移时间的影响因素

The Factors Influencing Migration Time in Capillary Ion Analysis

摘要: 定量考察了毛细管离子分析中温度及离子浓度对迁移时间的影响。实验证明，随温度升高迁移时间缩短；不同样品中同一离子的迁移时间随离子浓度增大而规律性缩短。探索了阴离子分析中等迁移时间模式的应用情况及其存在的问题，指出了仪器分离室温度恒定的重要性和等迁移时间模式的应用有助于解决离子浓度相差较大的样品分离定性问题。

Abstract: Influences of temperature and ion concentration on ion migration time in capillary ion analysis are studied. The experiments prove that ion migration time shortens with a rise in temperature and the migration time for the same ion in different samples sho
