HPLC Column, NP Amino, Wide Pore, 3um, 2.1mm ID x 100mm Length, 300A. Cogent Brand. 1 EA.
This Cogent NP Amino™ Wide Pore Stationary Phase has been a 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, to the highest purity silica available. This makes this column ideal as an Alternate in USP Methods that use the L8 Classification, for large molecules.
With a 3 µm Particle and 300A Pore Size, this column performs well for polar molecules with a negative charge such as complex Sugars and larger compounds with Carboxylic Acid Groups using Normal Phase or HILIC modes.
These columns are packed and shipped in Normal Phase Solvents. 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 often used with LCMS.
