YMC-Pack NH2 Product Details

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
