HPLC Column, NP Amino, Wide Pore, 3um, 2.1mm ID x 100mm Length, 300A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino™ Wide Pore is a normal-phase and HILIC stationary phase designed for the retention and separation of larger, highly polar compounds. Manufactured using a three-carbon propyl ligand with a terminal amino functional group bonded to ultra-high purity silica, this 300 Å wide pore stationary phase provides enhanced accessibility for larger analytes while maintaining the selectivity associated with USP L8 chemistry. It is an excellent choice as an alternative in USP methods requiring L8 functionality and for method development involving larger polar molecules.
68340-10P-2-3M is an HPLC column packed with 3 µm NP Amino™ Wide Pore particles featuring a 300 Å pore size in a 2.1 mm ID x 100 mm format. This narrow-bore configuration combines enhanced chromatographic resolution, reduced solvent consumption, and compatibility with LC-MS instrumentation. The wide pore structure improves mass transfer and accessibility for larger analytes, while the 100 mm length provides greater resolving power than shorter column formats. Typical operating flow rates are approximately 0.2–0.3 mL/min. Because of the low flow rates required by 2.1 mm ID columns, standard HPLC systems must be capable of precise and reproducible low-flow operation.
This column is particularly useful for complex sugars, larger compounds containing carboxylic acid groups, and other highly polar analytes analyzed using Normal Phase or HILIC chromatography. The amino functionality provides strong retention for polar molecules, while the 300 Å pore structure accommodates larger analytes that may be restricted on traditional 100 Å materials. The 2.1 mm ID format is frequently used for LC-MS applications requiring reduced solvent consumption and improved sensitivity. As an unmodified silica bonded amino phase, this column is also suitable for HILIC applications.
