Prep HPLC Column, RP Phenyl, 10um, 100A. 21.2mm ID x 250mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Phenyl is MICROSOLV's most popular phenyl stationary phase for reversed-phase HPLC and LC-MS applications. Built on high-purity silica with a C3-phenyl bonded phase and exhaustive double endcapping, it provides balanced hydrophobic retention combined with strong π-π interactions. This unique selectivity is particularly useful when C18 or C8 columns do not adequately resolve aromatic, heteroaromatic, or structurally related compounds.
68024-P21-250 is a preparative HPLC column packed with 10 µm RP Phenyl particles featuring a 100 Å pore size in a 21.2 mm ID x 250 mm format. The large internal diameter provides substantial sample loading capacity, while the 250 mm length maximizes chromatographic efficiency and resolving power for demanding purifications. The larger particle size supports higher flow rates with lower operating backpressure, making the column suitable for scale-up, process development, and preparative isolation. Typical operating flow rates are approximately 15–40 mL/min depending on sample load, mobile phase composition, and system capabilities.
This column is particularly effective for purification of positional isomers, aromatic pharmaceuticals, tocopherols, flavonoids, polynuclear aromatic compounds, nitro-aromatic compounds, active pharmaceutical ingredients (APIs), natural products, and related aromatic compounds. The scalable RP Phenyl chemistry enables straightforward transfer from analytical methods to preparative purification workflows.
