This Cogent NP Amino™ Wide Pore Stationary Phase has been a premium value and used by HPLC laboratories for many years. Not end capped, it is manufactured using a 3 carbon Ligand (propyl) with a terminal amino group bonded to world class, wide pore silica. This column is ideal as an Alternate in any USP Method that uses the L8 Classification or for new methods with larger molecules.

With a 10 µm Particle and 300A Pore Size, this column works well with higher flow rates and lower back pressures. Used for polar molecules with a negative charge such as complex Sugars and larger compounds with Carboxylic Acid Groups in Normal Phase or

HILIC

modes these columns are packed and shipped in Normal Phase Solvents.
