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.

 NH2-MS
USP code L8
Silica gel High purity porous spherical silica
Average particle size 5 µm
Average pore size approx. 300Å
Specific surface area approx. 120m2/g
Stationary phase Aminopropyl group
Bonding Type Polymeric
End capping treatment Near-perfect treatment

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.

Column size: 4.6 mm I.D. x 250 mm
Flow rate: 1 ml/min
Temperature: 30°C
Detection: RI
Sample: 1. Glucose
2. Maltose
