Grom Sapphire 110 C4

Low Hydrophobicity HPLC Column for Peptide and Small Biomolecule Analysis

Grom Sapphire 110 C4 is a silica-based HPLC column with a butyl (C4) bonded phase on high-purity 110 Å silica. Compared to longer-chain alkyl phases such as C18 or C8, the shorter C4 chains provide reduced hydrophobic retention, enabling faster elution and improved resolution for moderately hydrophobic or amphiphilic compounds.

The 110 Å pore size offers an optimal balance between surface area and accessibility, making Sapphire 110 C4 particularly suited for peptides, small biomolecules, and moderately hydrophobic analytes. Its robust bonding chemistry ensures sharp peak shapes, reproducibility, and long operational lifetime.

Grom Sapphire 110 C4 provides reliable performance with reduced hydrophobic selectivity – the dependable choice for laboratories analyzing peptides, small biomolecules, and moderately hydrophobic analytes in HPLC.

Key Features:

  • High-purity silica stationary phase with butyl (C4) bonded chemistry

  • 110 Å pore size for small molecules and peptides

  • Reduced hydrophobic retention compared to C18 or C8 phases

  • Robust bonding ensures reproducibility and long column lifetime

  • Available particle size: 5 µm
