Catalog Number - 68512-15P-4

Cogent RP C12™ HPLC Columns are designed for reversed-phase separations requiring unique selectivity, rapid equilibration, and reproducible retention. The stationary phase is manufactured using a rigid adamantane-shaped carbon silane ligand bonded to ultra-high purity silica and fully double end capped to minimize secondary interactions. This distinctive bonded phase chemistry offers chromatographic behavior between traditional C8 and C18 phases, making it especially useful for complex mixtures, analytical method development, and high-throughput screening applications.

68512-15P-4 is packed with 5 µm RP C12™ particles featuring a 100 Å pore size in a 4.0 mm ID x 150 mm format. The 150 mm column length provides enhanced resolving power and peak capacity compared to shorter columns, making it well suited for more demanding analytical separations. The RP C12™ phase typically provides less retention than C18 columns but greater retention than C8 columns for many hydrophobic compounds, offering an alternative selectivity profile that can improve challenging separations. The stationary phase is also compatible with highly aqueous mobile phases, including 100% water, without phase collapse or loss of retention.

The 4.0 mm ID x 150 mm format is commonly used for routine analytical HPLC, pharmaceutical analysis, quality control testing, and method development workflows. Typical flow rates are approximately 0.8-1.2 mL/min depending on method requirements and mobile phase conditions.
