Process HPLC Column, RP C8 Octyl, 10um, 100A. 50mm ID x 250mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C8 Octyl is a reversed-phase process HPLC stationary phase manufactured using high-purity silica with traditional octyl (C8) silane bonding and complete double endcapping. The moderate hydrophobicity of the C8 ligand provides lower retention than C18 phases while maintaining effective retention of hydrophobic and neutral compounds. This selectivity makes the phase an excellent choice for process-scale purification workflows where high recovery, efficient fraction collection, and loading capacity are critical.
68008-P50-250 is a process HPLC column with dimensions of 50 mm ID x 250 mm length, packed with 10 µm RP C8 Octyl particles featuring a 100 Å pore size. The extra-large internal diameter provides exceptionally high sample loading capacity for production-scale purification, while the 250 mm length delivers maximum resolving power and peak capacity for demanding separations. The 10 µm particle size supports high flow rates with lower operating backpressure, making this column well suited for process development, pilot-scale production, and manufacturing applications. Typical operating flow rates are approximately 80–200 mL/min depending on sample load, mobile phase composition, and system capabilities.
Designed for purification and fraction collection rather than routine analytical HPLC, this column is ideal for isolating hydrophobic or neutral compounds in pharmaceutical manufacturing, process chromatography, natural product purification, production support, and large-scale process development. The extended column length can significantly improve separation of closely related compounds and help achieve higher purity during process-scale isolations. Analytical methods are typically developed and optimized on analytical columns before transfer to preparative and process-scale columns such as this one. A specialized process HPLC system capable of high flow rates, large injection volumes, and large-scale fraction collection is required. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
