HPLC Column, RP C4 Butyl, 10um, 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 manufactured using high-purity silica with traditional butyl (C4) ligand bonding and complete double endcapping. Classified as USP L26, this stationary phase provides moderate hydrophobic retention and is well suited for compounds that may be overly retained on more hydrophobic phases such as C8 or C18 columns. The C4 chemistry offers reliable selectivity for hydrophobic and neutral analytes while maintaining shorter retention times than longer alkyl-chain phases.
68004-10P-4 is a 100 mm x 4.0 mm ID analytical HPLC column packed with 10 µm RP C4 Butyl particles featuring a 100 Å pore size. The 100 mm length provides an effective balance between analysis speed and chromatographic resolution, making it suitable for routine analytical testing, method development, and preparative method scouting. The 10 µm particle size supports higher flow rates with lower operating backpressure, while the 4.0 mm ID format is commonly selected for legacy methods and conventional HPLC systems and typically operates at approximately 0.8–1.5 mL/min.
This USP L26 column is particularly useful for hydrophobic and neutral compounds requiring less retention than a C8 phase. The combination of fully endcapped C4 chemistry, high-purity silica, and larger particle size provides robust chromatographic performance and method flexibility for analytical and preparative workflow development. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
