COSMOSIL NH2-MS
Saccharide Separation
The COSMOSIL 5NH2-MS is a column with aminopropyl group bonded silica packing material. It is recommended for separation of monosaccharides and oligosaccharides. While Sugar-D is our first choice for separation of saccharide, 5NH2-MS can give better separation than Sugar-D in some cases depending on samples.

Comparison of Retention
The conventional aminopropyl column is slightly more retentive than Sugar-D. The retention time can be adjusted by increasing the concentration of acetonitrile in the mobile phase by 5%-10% as shown below.
