HPLC Column, NP Amino, 10um, 4.6mm ID x 100mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino is a versatile normal phase and HILIC stationary phase designed for retention of highly polar compounds that are often difficult to retain using conventional reversed-phase columns. Manufactured on high-purity silica with a propyl amino bonded phase, it provides excellent selectivity for carbohydrates, sugars, organic acids, and other 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.
68040-10P is an analytical HPLC column packed with 10 µm NP Amino particles featuring a 100 Å pore size in a 4.6 mm ID x 100 mm format. The 100 mm length provides increased resolution compared to shorter columns while maintaining efficient analysis times. The 10 µm particle size supports higher flow rates and lower operating backpressure, making it suitable for routine analysis, method development, and preparative method scouting. Typical operating flow rates are approximately 1.0–2.0 mL/min depending on analyte properties, mobile phase composition, and instrument configuration.
This column is particularly effective for sugars, carbohydrates, negatively charged compounds, organic acids, carboxylic acid-containing compounds, and other highly polar molecules. As with all amino phases, it is suitable for both Normal Phase and HILIC applications when enhanced retention of polar analytes is required.
