Catalog Number - 68508-15P-4-3M

Cogent RP C8™ Wide Pore HPLC Columns are designed for reversed-phase separations of larger molecules that require enhanced pore accessibility and efficient mass transfer. The stationary phase consists of a traditional octyl (C8) bonded ligand attached to ultra-high purity silica and is fully double end capped to minimize secondary interactions while providing reproducible retention, excellent peak shape, and long column life. The 300 Å wide pore structure allows proteins, peptides, and other higher molecular weight compounds to access more of the bonded surface area, making this phase particularly suitable for biomolecule analyses and challenging large-molecule separations.

68508-15P-4-3M is packed with 5 µm RP C8™ Wide Pore particles featuring a 300 Å pore size in a 4.0 mm ID x 150 mm length format. The 150 mm column length provides high resolving power and increased peak capacity for complex analytical separations. The wide pore architecture improves accessibility and mass transfer for proteins, peptides, and long-chain fatty acids that may be partially excluded from conventional 100 Å media. The RP C8™ chemistry provides lower hydrophobic retention than comparable C18 phases while maintaining excellent selectivity for hydrophobic and moderately non-polar compounds.

The 4.0 mm internal diameter offers an effective balance between sensitivity, solvent consumption, and compatibility with traditional analytical HPLC instrumentation. This column configuration is well suited for protein and peptide analysis, pharmaceutical and biopharmaceutical testing, method development, and routine analytical workflows where high resolution and reliable performance are required.
