介绍了开管毛细管柱离子色谱的结构和初步表征。提高塔柱温度可显著提高塔柱效率。研究了两种不同的毛细管离子色谱柱。一种是50μm直径的熔融石英毛细管，另一种是50μm直径的涂覆乳胶颗粒的硅胶毛细管（直径约为360nm）。两种色谱柱均表现出良好的无机阴离子分离效果，但涂有乳胶颗粒的毛细管比裸露的二氧化硅毛细管保留率要大得多。
Construction and preliminary characterization of open tubular capillary column ion chromatography is described. Increasing the column temperature resulted in a dramatic increase of the column efficiency. Two different kinds of columns were developed and investigated for capillary ion chromatography. One was a 50μm i.d. fused silica capillary tubing, and another was a 50μm i.d. silica capillary coated with Latex particles (diameter: about 360nm). Both columns showed good separations of inorganic anions, although the capillary coated with Latex particles showed much larger retention than a bare silica capillary.
