Normal Phase Columns for Saccharides: Asahipak NH2P-50
Saccharides are separated by partition/adsorption mode (normal phase) in these
columns. Suitable for separation of monosaccharide, oligosaccharide and sugar
alcohol.

Eluent conditions:
(1) Water, acetonitrile and ethanol, either
singly or in mixtures of any ratio, may be
used as eluent. With aqueous ethanol solution
the flow rate should he lower than normal,
because of their relatively high viscosity.
(2) Various types of buffers soluble in acetonitrile
or ethanol (such as tetrapropylammonium acetate
or sodium acetate) may be used together with
the above components, so long as no observable
precipitation ocurs in the eluent.
