GromSil Octyl-5 CP

C8 Reversed-Phase Column with Classic Bonding for Reliable Routine Separations

GromSil Octyl-5 CP is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica and bonded with octyl (C8) ligands. The classic bonding and consistent surface chemistry provide moderate hydrophobic retention and reproducible separation of small to medium-sized molecules. Its retention behavior is ideal for analytes that elute too slowly on C18 phases, allowing for shorter run times and optimized method flexibility.

This column is suitable for a wide range of routine reversed-phase applications in pharmaceutical, environmental, and chemical laboratories.

With dependable performance and balanced retention, GromSil Octyl-5 CP from Dr. Maisch HPLC GmbH is a solid choice for robust and reproducible reversed-phase separations in daily laboratory workflows.

Key Features:

  • Octyl (C8) bonded reversed-phase phase – USP L7 classification

  • Fully porous, high-purity silica for consistent retention

  • Moderate hydrophobic interaction for improved elution times
