This Cogent NP Amino™ Stationary Phase is a premium value and used by HPLC laboratories all over the world. 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 and small particle columns or for new methods.
The small, 1.8µm Particle Size will provide high efficiency even at high flow rates and the Peak Capacity is greater than a 3um Particle. Higher back pressures than with larger particle columns are typical and a special UHPLC instrument may be required for proper results.
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
Note: A specialized UHPLC System is required for this column and your samples should be filtered with a 0.2 µ m Syringe Filter before injection.
