Additional Info: This Cogent RP C4™ Wide Pore Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is double end capped (fully), with traditional bonding of a 4 (Butyl) carbon ligand to the highest purity silica available. This makes this column ideal as an Alternate in USP Methods that use the L26 Classification, for large molecules.
With a 10 µm Particle and 300A Pore Size, this column works well with higher flow rates and lower back pressures. Used for proteins, peptides, enzymes and other large, hydrophobic or neutral compounds in Reversed Phase, this Butyl Phase is excellent for bioanalysis.
