In this study, open tubular capillary columns for ion chromatography were developed to analyze trace amount of ions in samples. When small I.D. capillary columns are used in ion chromatography, the typical flow rate of the mobile phase is 1~10 μL/min and the typical column length is 1.0~5.0 m. The capillary columns were made using fused silica capillary(I.D.: 50 μm) and DMEOHA latex particles. The new conductivity cell and suppressor were also developed and made for capillary column ion chromatography. When several anions(fluoride, nitrite, nitrate, chlorate, phosphate, sulfate) were analyzed using these capillary columns, reproducible and good chromatograms were obtained.
