Prep HPLC Column, RP C4, 5um, 100A. 30mm ID x 50mm Length. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C4™ is a reversed-phase HPLC stationary phase designed for the purification and isolation of hydrophobic and neutral compounds. Manufactured using a four-carbon butyl ligand bonded to ultra-high purity silica and fully double end capped, this stationary phase provides reproducible chromatographic performance and reduced hydrophobic retention compared to C8 and C18 phases. The chemistry is particularly useful for preparative-scale separations where efficient recovery and purification of target compounds are required.
68504-P30-50 is a preparative HPLC column packed with 5 µm RP C4™ particles featuring a 100 Å pore size in a 30 mm ID x 50 mm format. The large internal diameter provides exceptional sample loading capacity, while the shorter 50 mm length is optimized for faster purification cycles and higher throughput. The 5 µm particles provide lower operating backpressure than smaller particle sizes, making the column well suited for preparative HPLC systems. Typical operating flow rates are approximately 30–60 mL/min depending on mobile phase composition, analyte characteristics, and system capabilities.
This column is particularly useful for the purification of hydrophobic and neutral compounds in pharmaceutical, chemical, and research laboratories. Compared to C8 and C18 phases, the C4 bonded phase generally provides lower retention, which can improve recovery and reduce purification cycle times. The 30 mm ID format provides very high loading capacity for preparative applications, while the 50 mm length is ideal for rapid purification and fraction collection. A specialized preparative HPLC system is required for operation.
