SUPELCOGEL™ Ag1, 6% Crosslinked HPLC Column, 9 µm particle size, L x I.D. 30 cm x 7.8 mm, AG1

The Supelcogel Ag1 HPLC column 300x7.8mm, 9µm, contains a sulfonated polystyrene-divinylbenzene resin in the silver form with 6% crosslinking. By ligand exchange, Supelcogel Ag1 separates oligosaccharides according to their size and the spatial arrangement of their hydroxyl groups. The more highly crosslinked polymer structure enables rapid separations of smaller to medium oligomers up to about DP7. Typical applications are carbohydrate profiles in beer, dark corn syrup and starch hydrolysates as well as the simultaneous determination of sugars, glycerol and ethanol.

Features and Benefits

• Polymer-based ion-exclusion and ligand-exchange phases
• For sugars, sugar alcohols, and organic acids
• Various counterions available
• Stable in aqueous eluents
• Suitable for food and fermentation analysis

Additional Notes

Supelcogel columns are based on sulfonated, cross-linked polymer resins. Depending on the counterion, separation occurs via ligand exchange, ion exclusion, and size exclusion mechanisms. Calcium, lead, hydrogen, and other ion forms alter the selectivity for mono-, di-, and oligosaccharides, sugar alcohols, organic acids, and alcohols. As a result, Supelcogel is a proven platform for carbohydrate, food, beverage, and fermentation analysis.
