Waters™ IC-Pak™ columns are polymer-based HPLC columns for ion chromatography.
IC-Pak™ Anion columns are based on polymethacrylate resin with a quaternary ammonium functional group. They are suitable for the analysis of inorganic anions.
IC-Pak™ Cation columns are based on cross-linked styrene divinylbenzene resin with a sulfonic acid functional group. They are suitable for the analysis of mono- and divalent cations (in separate runs with different mobile phase compositions).
IC-Pak™ Ion-Exclusion columns are based on cross-linked styrene divinylbenzene resin with a sulfonic acid functional group. The columns are suitable for the analysis of organic acids, alcohols and carbohydrates via ion exclusion chromatography.
IC-Pak™ C M/D columns are strong cation exchange resins made of porous silica coated with polybutadiene-maleic acid copolymer. The columns allow a simultaneous analysis of monovalent and divalent cations under isocratic conditions.
