HPLC Column, RP C4 Butyl, 5um, 2.1mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
This Cogent RP C4™ 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, making this column ideal as an Alternate in USP Methods that use the L26 Classification.
With a 5 µm Particle, this column works well with higher flow rates and lower back pressures compared with smaller particles. Used for very hydrophobic or neutral compounds in Reversed Phase, this Butyl Phase is excellent for short analyses of small molecules. Expect Less retention than with a C8 column.
This narrow-bore column provides great data but requires a pump that can precisely deliver, and a flow cell thats made for, reduced flow rates with lower volumes. This column size is excellent, and a favorite for LCMS.
