The CarboPac? MA1 column is a high-capacity, strong anion-exchange column that delivers sensitive, rugged, and reliable separations of reduced sugars without the need for derivatization. The MA1 consists of a macroporous resin fully functionalized with a tertiary amine.
Recommended for the separation of reduced mono- and disaccharides
No derivatization needed
Separations using a simple hydroxide eluent
Alditols and aldoses separated from one another in a single run
Designed for reduced mono- and disaccharide alditol analyses, the CarboPac MA1 is also well suited for analysis of exoglycosidase-released neutral monosaccharides. Monosaccharides are moved away from the column void, enabling immediate evaluation of contaminating exoglycosidase activities. The MA1 can provide baseline resolution of fucose, N-acetyl-(D)-glucosamine, N-acetyl-galactosamine, mannose, glucose, and galactose, as well as neutral oligosaccharides in the same separation.

Gradient separation of alditols and aldoses potentially released by hydrolysis of beta eliminated oligosaccharides. Arabitol serves as an internal standard.
HPAE separation of sugars and sugar alcohols without the need for derivatization.
Isocratic separation of a representative set of alditols and aldoses ensures lot-to-lot reproducibility in the manufacturing of the CarboPac MA1 column.
