产品描述
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.
