SUPELCOGEL™ Ag2, 6% Crosslinked HPLC Column, 9 µm particle size, L x I.D. 30 cm x 7.8 mm, AG2

The Supelcogel Ag2 HPLC column 300x7.8mm, 9µm, is based on a sulfonated polystyrene-divinylbenzene resin in the silver form with a lower crosslinking degree of 4%. The more open polymer structure of the Supelcogel Ag2 facilitates access to the resin for larger oligosaccharides and extends the separation range up to and including DP12. The phase is used for corn syrup, starch hydrolysates and other complex oligosaccharide mixtures when higher molecular weight saccharides are to be differentiated.

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.
