HPLC Column, NP Amino, Wide Pore, 3um, 4.0mm ID x 50mm Length, 300A. Cogent Brand. 1 EA. Special Order Item.
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.
68340-05P-4-3M is an HPLC column packed with 3 µm NP Amino™ Wide Pore particles featuring a 300 Å pore size in a 4.0 mm ID x 50 mm format. The short 50 mm length is optimized for rapid analyses and increased sample throughput, while the wide pore structure improves mass transfer and accessibility for larger analytes. The 3 µm particles provide greater efficiency and sharper peaks than comparable 5 µm columns. Typical operating flow rates are approximately 0.8–1.5 mL/min depending on mobile phase composition, temperature, and system configuration.
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. As an unmodified silica bonded amino phase, this column is also suitable for HILIC applications.
