Catalog Number - 68524-P21-1503M

Cogent RP Phenyl™ Wide Pore Preparative HPLC Columns are designed for high-capacity purification, preparative separations, and process development involving larger aromatic compounds and structurally related analytes. Manufactured using ultra-high purity silica bonded with a three-carbon linker and terminal Phenyl functionality, this stationary phase is fully double end-capped to minimize secondary interactions and provide highly reproducible chromatographic performance. The 300Å wide pore structure improves analyte accessibility for larger molecules while maintaining the unique aromatic selectivity characteristic of RP Phenyl™ chemistry.

68524-P21-1503M is packed with 5 µm RP Phenyl™ Wide Pore particles in a 21.2 mm ID x 150 mm preparative format. The combination of 5 µm particles and 300Å pores provides efficient mass transfer for larger compounds while supporting preparative flow rates with manageable operating pressures. The large internal diameter and longer column length provide both high loading capacity and enhanced resolution, making this column well suited for demanding purification applications.

The 21.2 mm ID x 150 mm format is ideal for purification of larger positional isomers, tocopherols, flavonoids, polynuclear aromatic hydrocarbons, nitro-aromatic compounds, active pharmaceutical ingredients (APIs), natural products, peptides, and related aromatic compounds. Typical operating flow rates are approximately 15–25 mL/min depending on mobile phase composition, system pressure limitations, and application requirements. A specialized preparative HPLC system capable of supporting these flow rates and sample loads is required.
