Semi Prep HPLC Column, RP Phenyl, 10um, 100A. 10mm 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 combines hydrophobic retention with strong π-π interactions to provide enhanced selectivity for aromatic and structurally related compounds that may not separate sufficiently on traditional C18 or C8 columns.
68024-SP250 is a semi-preparative HPLC column packed with 10 µm RP Phenyl particles featuring a 100 Å pore size in a 10 mm ID x 250 mm format. The larger internal diameter provides increased sample loading capacity compared to analytical columns, while the 250 mm length maximizes resolving power and peak capacity for demanding purifications. The 10 µm particle size supports higher flow rates with lower operating backpressure, making this column well suited for purification, fraction collection, and method scale-up. Typical operating flow rates are approximately 4–12 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 RP Phenyl chemistry provides a scalable pathway from analytical method development to semi-preparative purification workflows.
