SiliaChrom IEC series are composed of a PS polymer-based packing bearing different functionnalities such as weak or strong cationic and anionic functions. SiliaChrom IEC phases are compatible with most mobile phase solvents and samples with a pH range from 1 to 14. Polymer-based columns tend to have lower efficiencies for small molecules compared to silica-based columns due to their smaller average surface area. Nevertheless, SiliaChrom IEC packing is a good alternative for samples that require a mobile phase pH outside the normal operating range of standard silica-based columns. SiliaChrom IEC columns are generally used for ion-exchange separations, and are also useful in non-aqueous GPC size-exclusion analysis and ion exclusion analysis of organic acids and carbohydrates.
