Catalog Number - 68540-SP150

Cogent NP Amino™ Semi-Preparative HPLC Columns are designed for purification, method development, and scale-up of polar compounds using Normal Phase and HILIC chromatographic modes. Manufactured using world-class silica bonded with a three-carbon propyl ligand containing a terminal amino functional group, this stationary phase provides unique selectivity for negatively charged and highly polar analytes. NP Amino™ is widely used as an alternative for USP L8 methods and for new method development involving carbohydrates, organic acids, and other polar compounds.

68540-SP150 is packed with 5 µm NP Amino™ particles in a 10 mm ID x 150 mm semi-preparative format with a 100Å pore size. The 5 µm particle size delivers excellent chromatographic efficiency while supporting higher sample loading than analytical columns. The 10 mm internal diameter provides increased loading capacity for purification and method scale-up applications, while the 150 mm column length offers enhanced resolution and retention for more demanding separations.

The NP Amino™ stationary phase is not end capped and is commonly used for compounds containing carboxylic acid functionalities, sugars, and other polar analytes that require Normal Phase or HILIC retention mechanisms. These columns are packed and shipped in Normal Phase solvents and are frequently selected for transferring analytical methods to semi-preparative purification workflows.
