Prep HPLC Column, NP Amino, Wide Pore, 10um, 300A. 21.2mm ID x 50mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino Wide Pore is a versatile normal phase and HILIC stationary phase designed for retention of highly polar compounds and larger molecules that are often difficult to retain using conventional reversed-phase columns. Manufactured on high-purity 300 Å wide pore silica with a propyl amino bonded phase, it provides excellent selectivity for complex carbohydrates, sugars, organic acids, and other highly polar analytes. This stationary phase is commonly used as an alternative for USP L8 methods and is suitable for both Normal Phase and HILIC separations involving larger molecular species.
68040-P21-50-3M is a preparative HPLC column packed with 10 µm NP Amino Wide Pore particles featuring a 300 Å pore size in a 21.2 mm ID x 50 mm format. The large internal diameter provides substantial sample loading capacity for purification workflows, while the short 50 mm length is optimized for rapid method development, preparative screening, and scale-up studies. The 10 µm particle size supports higher flow rates with lower operating backpressure, while the wide pore structure improves accessibility for larger molecules. Typical operating flow rates are approximately 15–40 mL/min depending on sample load, mobile phase composition, and system capabilities.
This column is particularly effective for complex sugars, carbohydrates, negatively charged compounds, organic acids, carboxylic acid-containing compounds, and other highly polar molecules. The wide pore design provides improved performance for larger analytes in both Normal Phase and HILIC applications. As with all amino phases, this column is suitable for HILIC applications when enhanced retention of polar compounds is required.
