的詳細介紹
CarboPac MA1 Column for Carbohydrate, Alditol, and Aldose Analysis
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.
