HPLC Column, RP C4 Butyl, 3um, 4.0mm ID x 100mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C4 Butyl™ is a reversed-phase HPLC stationary phase designed for the separation of hydrophobic to moderately hydrophobic compounds. Manufactured using a traditional butyl (C4) bonded phase on ultra-high purity silica and fully double end capped, it provides excellent reproducibility, reliable peak shape, and balanced retention characteristics. As a USP L26 equivalent phase, it is commonly used as an alternative for compendial methods and for applications where lower hydrophobic retention than C8 or C18 phases is preferred.
68304-10P-4 is an HPLC column packed with 3 µm RP C4 Butyl™ particles featuring a 100 Å pore size in a 4.0 mm ID x 100 mm format. The 100 mm length provides greater resolution and peak capacity than shorter 50 mm columns, while the 3 µm particles deliver improved efficiency and sharper peaks compared to traditional 5 µm packings. Typical operating flow rates are approximately 0.8–1.5 mL/min depending on mobile phase composition, temperature, and system configuration.
This column is particularly useful for hydrophobic and neutral compounds analyzed by reversed-phase HPLC. The C4 chemistry provides lower retention than C8 phases, making it advantageous when faster elution and shorter run times are desired without sacrificing chromatographic performance.
