Amino column with improved durability.

YMC-Pack Polyamine II is a silica-based, normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars. The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases. In addition, YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes.


  • Silica gel chemically bonded to polyamine
