GromSil 100 ODS-2 FE

Fully Endcapped C18 Reversed-Phase Column for High Peak Symmetry and Reproducibility

GromSil 100 ODS-2 FE is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with fully porous, high-purity silica with a 100 Å pore size and bonded with octadecyl (C18) ligands. The phase features full endcapping (FE), effectively masking residual silanol groups to minimize secondary interactions. This results in excellent peak symmetry, reduced tailing, and highly reproducible retention — especially for basic and ionizable compounds.

The column is ideal for pharmaceutical and chemical analysis where precision, robustness, and regulatory compliance are essential.

Offering high stability and consistent retention, the fully endcapped C18 phase from Dr. Maisch HPLC GmbH is well suited for demanding reversed-phase HPLC applications in regulated and research environments.

Key Features:

  • Octadecyl (C18) bonded reversed-phase phase with full endcapping – USP L1

  • Fully porous silica with 100 Å pore size

  • Suppressed silanol activity for enhanced peak shape and reproducibility

  • Strong hydrophobic retention suitable for a broad analyte range

  • Available in 3 µm, 5 µm, and 10 µm particle sizes

Typical Applications:

  • Basic drug substances and pharmaceutical impurities

  • LC-MS and UV-based reversed-phase method development

  • Robust quality control and validated analytical procedures

  • General-purpose separations with high column efficiency
