This Cogent NP Amino™ 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 silica. This column is ideal as an Alternate in any USP Method that uses the L8 Classification or for new methods.
Used for polar molecules with a negative charge such as Sugars and compounds with Carboxylic Acid Groups in Normal Phase or HILIC modes these columns are packed and shipped in Normal Phase Solvents.
A very popular column size, this narrow-bore column provides good run times but requires a pump that can precisely deliver, and a flow cell that is made for reduced flow rates with lower volumes. This column size is excellent, and a favorite for LCMS.
