HPLC Column, NP Amino, 5um, 4.6mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino™ HPLC Columns are designed for Normal Phase and HILIC separations of highly polar compounds. Manufactured using ultra-high purity silica bonded with a three-carbon propyl linker and terminal amino functionality, this stationary phase provides the selectivity needed for retention and separation of compounds that can be difficult to retain using traditional reversed-phase chromatography. NP Amino™ is an excellent alternative for USP L8 methods and for new method development involving polar analytes.
68540-15P is packed with 5 µm NP Amino™ particles in a 4.6 mm ID x 150 mm format with a 100Å pore size. The 5 µm particle size provides reliable performance with moderate backpressure while maintaining excellent reproducibility. The 150 mm column length offers enhanced resolving power compared to shorter columns, making it ideal for routine analytical methods, method development, and more challenging separations requiring increased retention and resolution.
The amino stationary phase is not end capped and is particularly useful for sugars, carbohydrates, organic acids, and other highly polar compounds containing hydroxyl or carboxylic acid functionalities. This column can be used in Normal Phase and HILIC chromatographic modes and is packed and shipped in normal-phase solvents. This is the most popular NP Amino™ column configuration and is frequently selected for USP methods requiring USP L8 chemistry.
