HPLC Column, RP C4 Butyl, Wide Pore, 3um, 2.1mm ID x 150mm 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.
This narrow-bore column provides excellent data and requires a pump that can precisely deliver, and a flow cell that is made for reduced flow rates with lower volumes. This column size is great for LCMS.
