COSMOSIL PBr column is packed with pentabromobenzyl bonded silica that enables separation by dispersion force interaction. COSMOSIL PBr enables separation of hydrophilic compounds in reversedphase conditions, maintaining sharp peak shapes even with aqueous samples. COSMOSIL PBr retains hydrophilic compounds, cyclic compounds or amide compounds stronger than C18 columns under the same reversed-phase conditions.
