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.
Characteristics
- Silica gel chemically bonded to polyamine
- The most suitable column for separation of sugars
- Solves durability problems of conventional silica-based amino columns
- Useful for separation of hydrophilic compounds, including vitamins
- Useful for separation of fat-soluble compounds using non-aqueous mobile phases
Applications
Typical applications include: sugars, vitamins, fat-soluble compounds
