GromSil 200 ODS-5 ST is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with fully porous, high-purity silica featuring a 200 Å pore size and bonded with octadecyl (C18) ligands. With standard endcapping (ST), this phase provides strong hydrophobic retention and reliable peak shape for a wide range of analytes — especially for larger or lipophilic molecules that require extended pore accessibility.
Designed for robust, cost-effective analysis, this column is suitable for both routine and exploratory reversed-phase applications in pharmaceutical, chemical, and academic laboratories.
Offering balanced performance and broad applicability, GromSil 200 ODS-5 ST from Dr. Maisch HPLC GmbH is an excellent choice for laboratories in need of reliable wide-pore C18 separations.
