Catalog Number - 68540-P30-50

Cogent NP Amino™ Preparative HPLC Columns are designed for high-capacity purification 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 for preparative separations involving carbohydrates, organic acids, and other polar compounds that can be difficult to retain using conventional reversed-phase chromatography.

68540-P30-50 is packed with 5 µm NP Amino™ particles in a 30 mm ID x 50 mm preparative format with a 100Å pore size. The 5 µm particle size provides excellent chromatographic efficiency while maintaining the substantial sample loading capacity required for preparative purification. The large 30 mm internal diameter offers very high loading capacity, while the short 50 mm length is ideal for rapid purification, method development, and high-throughput preparative workflows.

The NP Amino™ stationary phase is not end capped and is commonly used for purification of sugars, compounds containing carboxylic acid functionalities, and other negatively charged or highly polar analytes. These columns are suitable for both Normal Phase and HILIC separations and are shipped in Normal Phase solvents. The large-diameter preparative format supports efficient purification workflows while enabling rapid scale-up and fast fraction collection.
