Prep HPLC Column, RP C12, 10um, 100A. 21.2mm ID x 100mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C12 is a unique reversed-phase preparative HPLC stationary phase based on an adamantane bonded ligand, a rigid diamond-like carbon structure that provides distinctive chromatographic selectivity compared to traditional alkyl phases. The combination of high-purity silica, a narrow particle size distribution, low metal content, complete double endcapping, and the rigid bonded phase design makes this column particularly effective for purifying complex mixtures while supporting rapid equilibration between runs. The phase generally provides retention that falls between C8 and C18 columns, making it an excellent choice when C18 retention is excessive and C8 retention is insufficient.
68012-P21-100 is a preparative HPLC column with dimensions of 21.2 mm ID x 100 mm length, packed with 10 µm RP C12 particles featuring a 100 Å pore size. The large internal diameter provides substantial sample loading capacity for preparative purification, while the 100 mm length offers an effective balance between throughput and separation efficiency. The 10 µm particle size supports higher flow rates with lower operating backpressure, making this column well suited for purification, fraction collection, process development, and method scale-up. Typical operating flow rates are approximately 15–40 mL/min depending on sample load, mobile phase composition, and system capabilities.
Compatible with reversed-phase mobile phases, including 100% aqueous conditions, this column maintains reproducible retention without loss of performance between runs. The unique adamantane bonded phase can provide valuable selectivity advantages when purifying hydrophobic and moderately hydrophobic compounds from complex sample matrices. 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.
