Widely applied in chemical workflows, the HPLC Column Nucleodur® C 18 Gravity SB offers exceptional versatility for overall sophisticated analytical separations, particularly for polar compounds. With a particle size of 3 μm and a column volume of 0.87 ml, this analytical separation column delivers optimal performance under highly aqueous conditions. Its base deactivated (BDS), high density octadecyl (C 18, ODS) modification ensures hydrophobic (van der Waals) interactions with additional polar interactions, making it ideal for method development and applications such as antibiotics, organic acids, water-soluble vitamins, and antioxidants. This column's pressure stability of 600 bar and temperature stability of 60°C further enhance its robustness and reliability in various lab settings.
