HPLC Column, RP C4 Butyl, 10um, 4.0mm ID x 50mm 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 is commonly used for hydrophobic and neutral compounds, offering efficient separations with less retention than longer alkyl-chain stationary phases.
68004-05P-4 is a 50 mm x 4.0 mm ID analytical HPLC column packed with 10 µm RP C4 Butyl particles with a 100 Å pore size. The short 50 mm length is optimized for rapid analyses, screening studies, and method development applications where speed is important. The larger 10 µm particle size allows operation at higher flow rates while generating lower backpressure than smaller particle columns. 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 short analyses of hydrophobic and neutral compounds, as well as applications requiring less retention than a C8 column. The combination of fully endcapped C4 chemistry, high-purity silica, and larger 10 µm particles provides robust chromatographic performance for analytical method development and preparative method scouting applications. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
