Abstract
In this study, 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 $5{\sim}15{\mu}L/min$ and the typical column length is 50~150 mm. The capillary columns were made using RSL-300 fused silica capillary(I.D.: 0.53 mm, O.D.: 0.67 mm) and AG14 column resin(support : polystyrene-divinylbenzene, functional group : alkyl quaternary ammonium). The new conductivity cell and suppressor were also developed and made for capillary column ion chromatography. When several anions (fluoride, nitrite, nitrate, chlorate) were analyzed using these capillary columns, reproducible and good chromatograms were obtained.
