Semi Prep HPLC Column, RP C4, 5um, 100A. 10mm ID x 150mm Length. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C4™ is a reversed-phase HPLC stationary phase designed for the purification and isolation of hydrophobic and neutral compounds. Manufactured using a four-carbon butyl ligand bonded to ultra-high purity silica and fully double end capped, this stationary phase provides reproducible chromatographic performance and lower hydrophobic retention than C8 phases. The chemistry is particularly useful for semi-preparative applications where compound recovery, increased loading capacity, and efficient purification are required.
68504-SP150 is a semi-preparative HPLC column packed with 5 µm RP C4™ particles featuring a 100 Å pore size in a 10 mm ID x 150 mm format. The 10 mm internal diameter provides substantially greater sample loading capacity than analytical columns, while the 150 mm length offers increased chromatographic resolution and peak capacity compared to shorter semi-preparative columns. Typical operating flow rates are approximately 4–8 mL/min depending on mobile phase composition, analyte properties, and system capabilities.
This column is particularly useful for purification of hydrophobic and neutral compounds in pharmaceutical, chemical, and research laboratories. Compared to C8 and C18 phases, the C4 bonded phase provides lower retention, which can improve recovery and reduce purification cycle times. The 150 mm length is well suited for applications requiring higher resolution and improved separation performance. A semi-preparative HPLC system capable of the required flow rates is recommended for optimal performance.
