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.


  • Silica gel chemically bonded with aminopropyl groups
  • Useful for separation of sugars
  • Enables normal phase separation using aqueous or non-aqueous mobile phases


Typical applications include: saccharides, nucleotides, water-soluble vitamins
