A normal phase amino column.
YMC-Pack NH2 is a normal phase separation column utilizing the polarity of primary amino groups bonded to silica. It is a versatile stationary phase often used for the separation of sugars, but can also be used for separations utilizing weak anion-exchange.
Characteristics
- Silica gel chemically bonded with aminopropyl groups
- Useful for separation of sugars
- Enables normal phase separation using aqueous or non-aqueous mobile phases
Applications
Typical applications include: saccharides, nucleotides, water-soluble vitamins
