HPLC Column, NP Amino, 3um, 4.6mm ID x 50mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino™ is a normal-phase and HILIC stationary phase designed for the retention and separation of highly polar compounds. Manufactured using a three-carbon propyl ligand with a terminal amino functional group bonded to high-purity silica, this stationary phase provides selectivity that is particularly useful for carbohydrates, organic acids, and other polar analytes. As a USP L8 equivalent phase, it is widely used as an alternative in established USP methods and for new method development involving normal-phase or HILIC chromatography.
68340-05P is an HPLC column packed with 3 µm NP Amino™ particles featuring a 100 Å pore size in a 4.6 mm ID x 50 mm format. The short 50 mm length is optimized for rapid analyses and high-throughput workflows, while 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 the analysis of sugars, carbohydrates, compounds containing carboxylic acid groups, and other polar molecules. Suitable for both Normal Phase and HILIC chromatography, the amino functionality provides retention characteristics that make it valuable for applications where traditional reversed-phase columns may provide insufficient retention. As an unmodified silica bonded amino phase, it is also suitable for HILIC applications.
