Pre-packed columns, cartridges, and guard columns for separation of biomolecules and organic/inorganic analytes; includes normal/reversed phase HPLC, UHPLC, LC-MS, HILIC, mixed-mode, ion exchange, ligand exchange, and affinity column formats.
This Cogent Ion Exchange Column is a Strong Cation Exchanger (SCX a negatively charged surface ) Stationary Phase that has been a premium value and used by HPLC laboratories for many years. It is manufactured with Sulfonic Acid functional groups that are always charged. We use only the highest purity silica available, making this column ideal as an Alternate in USP Methods that use the L9 Classification or for "Bases" analysis or purification. With a 10µm Particle, this column works well with higher flow rates and lower back pressures for challenging IEX applications that include Cations (positive charge compounds).
