GromSil 80 ODS-7 pH is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with an 80 Å pore size and specially bonded octadecyl (C18) ligands. Designed for increased chemical stability, this phase is engineered to tolerate a broader pH range than conventional C18 materials, making it ideal for methods requiring either acidic or slightly basic mobile phases.
Its endcapped surface delivers reliable peak symmetry, reduced tailing, and consistent retention behavior across diverse analytical conditions.
With its expanded pH tolerance and stable chromatographic performance, GromSil 80 ODS-7 pH from Dr. Maisch HPLC GmbH is a versatile solution for laboratories seeking robust and flexible reversed-phase methods.
