Semi Prep HPLC Column, RP C4, 10um, 100A. 10mm ID x 250mm 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 while providing lower retention than C18 phases and greater retention than many C8 phases. The fully endcapped surface delivers reliable chromatographic performance and reproducible purification results for semi-preparative applications.
68004-SP250 is a semi-preparative HPLC column with dimensions of 10 mm ID x 250 mm length, packed with 10 µm RP C4 Butyl particles featuring a 100 Å pore size. The larger internal diameter provides increased sample loading capacity compared to analytical columns, while the 250 mm length provides maximum resolving power and peak capacity for demanding purification applications. The 10 µm particle size supports higher flow rates with lower operating backpressure. Typical flow rates are approximately 3–8 mL/min depending on mobile phase conditions, analyte properties, and system capabilities.
This column is intended for semi-preparative HPLC purification where target compounds are isolated and collected for further research, development, formulation, or production. The extended column length is particularly beneficial when separating closely related compounds, improving purity, or optimizing scale-up methods. Applications include pharmaceutical research, synthetic chemistry, natural product purification, reference standard preparation, and process development. A specialized HPLC system capable of semi-preparative 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.
