COSMOSIL PBr HPLC Columns
Hydrophilic interaction chromatography (HILIC) is an increasingly popular analytical technique. However, it is often difficult to develop a robust method due to users’ less familiarity with HILIC conditions. Furthermore, high concentration of acetonitrile used in HILIC mobile phase makes it extremely sensitive to samples’ water concentration; injecting samples in high water concentration often results in poor peak shapes. COSMOSIL PBr enables separation of hydrophilic compounds in reversed- phase conditions, maintaining sharp peak shapes even with aqueous samples.
