Equisorb NH2 is an aminopropyl-modified HPLC column based on fully porous, high-purity silica, designed for use in HILIC, normal-phase, and weak anion-exchange chromatography. The NH₂ functional group enables polar interactions such as hydrogen bonding and dipole-dipole retention, making this column ideal for the separation of carbohydrates, organic acids, and other hydrophilic analytes. Equisorb NH2 offers stable performance and cost-effective versatility across multiple chromatographic modes.
Equisorb NH2 offers reliable performance for polar separations – an ideal choice for HILIC, normal-phase, and sugar-specific chromatography in routine and research environments.
