HPLC Column, RP C12, 3um, 4.0mm ID x 100mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
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.
68312-10P-4 is an HPLC column packed with 3 µm RP C12™ particles featuring a 100 Å pore size in a 4.0 mm ID x 100 mm format. The 100 mm length provides greater chromatographic resolution than shorter 50 mm columns while maintaining practical analysis times for routine and research applications. The 3 µm particles provide greater efficiency and sharper peaks than comparable 5 µm columns, making this format an excellent balance between speed and resolving power. 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, making it an excellent choice for high-throughput screening (HTS), method development, and complex sample separations requiring enhanced resolution.
