HPLC Column, RP C8 Octyl, Wide Pore, 3um, 4.0mm ID x 150mm Length, 300A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C8 Octyl™ Wide Pore is a reversed-phase HPLC stationary phase specifically designed for the separation of large hydrophobic and neutral molecules. Manufactured using a traditional octyl (C8) bonded phase on ultra-high purity silica and fully double end capped, this 300 Å wide pore chemistry provides enhanced accessibility for larger analytes compared to standard 100 Å pore columns. As a USP L7 equivalent phase, it is particularly useful for proteins, peptides, long-chain fatty acids, and other compounds that benefit from improved pore accessibility and mass transfer.
68308-15P-4-3M is an HPLC column packed with 3 µm RP C8 Octyl™ Wide Pore particles featuring a 300 Å pore size in a 4.0 mm ID x 150 mm format. The 150 mm length provides enhanced chromatographic resolution and peak capacity compared to shorter column formats, making it well suited for demanding separations involving complex samples. The 3 µm particles provide higher efficiency and sharper peaks than comparable 5 µm columns, while the wide pore structure allows larger molecules to efficiently access the bonded phase for improved chromatographic performance. Typical operating flow rates are approximately 0.8–1.5 mL/min depending on mobile phase composition and system configuration.
This column is particularly useful for large hydrophobic or neutral compounds analyzed by reversed-phase HPLC. The C8 chemistry offers balanced hydrophobic retention while the 300 Å pore structure improves performance for larger analytes including proteins, peptides, and long-chain fatty acids. The 150 mm length provides additional resolving power for biopharmaceutical, research, and analytical applications requiring greater chromatographic efficiency.
