Prep HPLC Column, RP C8 Octyl, 10um, 100A. 30mm ID x 100mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C8 Octyl is a reversed-phase preparative 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 preparative purification workflows where high recovery, efficient fraction collection, and loading capacity are important.
68008-P30-100 is a preparative HPLC column with dimensions of 30 mm ID x 100 mm length, packed with 10 µm RP C8 Octyl particles featuring a 100 Å pore size. The extra-large internal diameter provides very high sample loading capacity for preparative-scale purification, while the 100 mm length offers an effective balance between purification efficiency and throughput. The 10 µm particle size supports higher flow rates with lower operating backpressure, making this column suitable for purification, process development, and production-support applications. Typical operating flow rates are approximately 30–80 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 research, synthetic chemistry, natural product purification, process development, and scale-up applications. Analytical methods are typically developed and optimized on analytical columns before transfer to preparative columns such as this one. A specialized preparative HPLC system capable of higher flow rates, larger injection volumes, and fraction collection is required. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
