Catalog Number - 68312-15P

Cogent RP C12™ is a unique reversed-phase HPLC stationary phase designed to provide balanced hydrophobic retention, rapid equilibration, and excellent reproducibility. Manufactured using a rigid adamantane-shaped carbon silane bonded to ultra-high purity silica and fully double end capped, this stationary phase offers selectivity that falls between traditional C8 and C18 phases. The distinctive ligand structure provides excellent performance for complex mixtures and applications requiring robust retention behavior across a wide range of mobile-phase conditions.

68312-15P is an HPLC column packed with 3 µm RP C12™ particles featuring a 100 Å pore size in a 4.6 mm ID x 150 mm format. The 150 mm length provides increased chromatographic resolution and peak capacity compared to shorter column formats, while the 3 µm particles provide greater efficiency and sharper peaks than comparable 5 µm columns. Typical operating flow rates are approximately 0.8–1.5 mL/min depending on mobile phase composition, temperature, and system configuration.

Compatible with virtually all reversed-phase mobile phases, including 100% aqueous conditions, this column maintains consistent retention without the phase collapse often associated with some traditional reversed-phase columns. Retention is typically greater than C8 phases but lower than C18 phases for the same hydrophobic compounds. As one of the most popular RP C12™ column configurations, it is frequently selected for high-throughput screening (HTS), method development, and routine analytical methods requiring enhanced resolution and reliable reproducibility.
