HPLC Column, NP Amino, 3um, 4.0mm ID x 250mm Length, 100A. Cogent Brand. 1 EA.
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.
With a 3µm Particle, this column is more efficient than a 5um column of the same phase and you will experience sharper peaks. However, due to the smaller particle size, there is an increased back pressure.
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.
