Allsphere Amino is an aminopropyl-modified HPLC column designed for multiple chromatographic modes, including HILIC, normal-phase, and carbohydrate-specific applications. Based on high-purity, fully porous silica, this phase provides polar retention and weak anion-exchange characteristics, enabling selective separation of hydrophilic, polar, and sugar-based analytes.
The amino functionality allows strong dipole and hydrogen bonding interactions, making Allsphere Amino a versatile choice for laboratories working in food analysis, bioanalytics, and polar compound profiling.
Allsphere Amino provides stable, reproducible performance for hydrophilic and carbohydrate-focused separations — a reliable tool for polar-phase chromatography in routine analysis.
