HPLC Column, RP C12, 10um, 4.6mm ID x 100mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C12 is a unique reversed-phase 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 resolving complex mixtures, fast gradient separations, and applications requiring 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.
68012-10P is an analytical HPLC column with dimensions of 4.6 mm ID x 100 mm length, packed with 10 µm RP C12 particles featuring a 100 Å pore size. The 100 mm column length provides increased resolving power compared to shorter columns while maintaining efficient analysis times. 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 flow rates for this 4.6 mm ID column are approximately 1.0–2.0 mL/min depending on mobile phase composition and system requirements.
Compatible with reversed-phase mobile phases, including 100% aqueous conditions, this column maintains reproducible retention without loss of performance between runs. Typical applications include pharmaceutical analysis, quality control testing, environmental analysis, method development, high-throughput screening, and complex mixture separations. The additional column length often provides improved resolution for challenging separations while still benefiting from the rapid equilibration characteristics of the RP C12 stationary phase. This column is also frequently used for preparative method scouting prior to scaling methods to larger diameter purification columns.
