Semi Prep HPLC Column, RP C12, 10um, 100A. 10mm ID x 250mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C12 is a unique reversed-phase semi-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-SP250 is a semi-preparative HPLC column with dimensions of 10 mm ID x 250 mm length, packed with 10 µm RP C12 particles featuring a 100 Å pore size. The 10 mm internal diameter provides significantly greater sample loading capacity than analytical columns, while the 250 mm length delivers maximum resolving power and peak capacity for demanding purification applications. The rigid adamantane bonded phase promotes rapid re-equilibration during gradient methods, while the 10 µm particle size supports higher flow rates and lower operating backpressure. Typical operating flow rates are approximately 8–15 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. Designed for purification and fraction collection rather than routine analytical HPLC, this column is ideal for pharmaceutical research, synthetic chemistry, natural product isolation, process development, and method scale-up. The extended column length maximizes separation efficiency and can improve purification of closely related compounds, helping achieve higher purity fractions. A specialized semi-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.
