HPLC Column, RP C4 Butyl, Wide Pore, 3um, 4.0mm ID x 250mm Length, 300A. Cogent Brand. 1 EA.
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.
With a 3µm Particle, this column is more efficient than a 5um column of the same phase and you will experience sharper peaks. However, due to the smaller particle size, there is an increased back pressure. Used for proteins, peptides, enzymes and other large, hydrophobic or neutral compounds in Reversed Phase, this Butyl Phase is excellent for bioanalysis.
