Polaris™ NH₂ is an aminopropylsilane-covered silica that can be used in either reversed or normal phase conditions. Exhibit higher efficiencies for carbohydrate analysis than ionic gel-based columns

• Mobile phase is acetonitrile/water
• Shorter gradient re-equilibration times

Monomolecular layer of aminopropylsilane chemically bonded to totally porous silica gel support, 10 µm in diameter.
