Prep HPLC Column, RP C4, 10um, 100A. 21.2mm ID x 150mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C4 Butyl is a reversed-phase HPLC stationary phase manufactured using high-purity silica with traditional butyl (C4) ligand bonding and complete double endcapping. The moderate hydrophobicity of the C4 ligand makes this stationary phase an excellent choice for purification of hydrophobic and neutral compounds that may be retained too strongly on C18 phases. The fully endcapped design provides reproducible separations and dependable performance for preparative-scale compound isolation.
68004-P21-150 is a preparative HPLC column with dimensions of 21.2 mm ID x 150 mm length, packed with 10 µm RP C4 Butyl particles featuring a 100 Å pore size. The larger internal diameter is designed for purification workflows where significantly greater sample loading is required than analytical columns can accommodate. The 150 mm length provides increased resolving power compared to shorter preparative columns, making it well suited for process development, scale-up studies, and purification methods requiring enhanced separation of closely related compounds. Typical flow rates are approximately 15–40 mL/min depending on mobile phase conditions and system capabilities.
This column is intended for preparative HPLC purification where target compounds are isolated and collected for further research, development, formulation, or production. Applications include pharmaceutical research, synthetic chemistry, natural product isolation, reference standard preparation, and pilot-scale purification. A specialized 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.
