HPLC Column, RP C8 Octyl, 5um, 2.1mm ID x 100mm Length, 100A. Cogent Brand. 1 EA.
This Cogent RP C8™ 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 8 (Octyl) carbon silane to the highest purity silica available, making this column ideal as an Alternate in USP Methods that use the L7 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 Octyl Phase is excellent for long chain fatty acids. Expect less retention than with a C18 column.
This column is often chosen for LCMS when increased resolution is desired.
