HPLC Column, RP C18, 5um, 3.9mm ID x 300mm Length, 100A. Cogent Brand. 1 EA.
Additional Info:
This Cogent RP C18™ 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 an 18 carbon silane to the highest purity silica available, making this column ideal as an Alternate in USP Methods that use the L1 Classification.
With a 5 µm Particle, this column works well with higher flow rates and lower back pressures compared with smaller particles. Used for hydrophobic or neutral compounds in Reversed Phase, this Octadecyl Phase is excellent for long chain fatty acids. Expect longer retention than with a C8 column.
This column size is chosen for Substitution for Older USP L1 Methods that require this dimension.
