GromSil 100 ODS-1 PE is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with high-purity, fully porous silica featuring a 100 Å pore size and bonded with octadecyl (C18) ligands. The phase undergoes partial endcapping (PE), which reduces—but does not eliminate—residual silanol activity. This design provides a balanced retention profile suitable for a wide range of analytes, while maintaining moderate polar interaction for selectivity enhancement.
This column is a robust and economical choice for routine reversed-phase separations in pharmaceutical, chemical, and environmental analysis.
Designed for dependable retention and versatile performance, the partially endcapped C18 phase from Dr. Maisch HPLC GmbH is ideal for robust, general-purpose reversed-phase HPLC applications.
