HPLC Column, RP Phenyl, Wide Pore, 5um, 4.6mm ID x 250mm Length, 300A. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Phenyl™ Wide Pore HPLC Columns are designed for reversed-phase separations involving larger molecules that benefit from aromatic selectivity and enhanced pore accessibility. 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 300 Å wide pore structure improves analyte access to the stationary phase, making this column an excellent alternative for USP L11 methods involving larger compounds and for new method development.
68524-25P-3M is packed with 5 µm RP Phenyl™ Wide Pore particles featuring a 300 Å pore size in a 4.6 mm ID x 250 mm format. The wide pore structure improves mass transfer for larger molecules, including peptides and complex natural products, while the 5 µm particle size provides excellent chromatographic efficiency with moderate operating pressures. The extended 250 mm column length delivers maximum resolution and peak capacity for demanding separations requiring enhanced analyte discrimination.
The 4.6 mm ID x 250 mm format is well suited for reversed-phase separations of large positional isomers, peptides, natural products, and related compounds. Typical flow rates are approximately 0.8-1.5 mL/min depending on mobile phase composition and application requirements. This format is particularly useful when maximum chromatographic resolution is required for complex samples.
