SUGAR SC1821 300x8mm Sugars

The SUGAR SC1821 HPLC column300x8.0mm, 6µm, contains sulfonic acid groups in calcium form on a sulfonated styrene-divinylbenzene resin. SUGAR SC1821 combines calcium-mediated ligand exchange with size exclusion and has an expanded pore structure compared with SC1011 with a nominal exclusion limit of about 10,000 Da for pullulan. Water serves as a typical mobile phase. Typical applications are mono-, di- and oligosaccharides as well as carbohydrate-containing food samples.

Features and Benefits

• Polymer-based carbohydrate phases
• Multiple defined counterions
• Ligand- and ion-exchange mechanisms
• Elution with pure water is often possible
• For sugars, acids, and fermentation samples

Additional Notes

The SUGAR product family is based on sulfonated styrene-divinylbenzene resins with defined counterions such as calcium, lead, sodium, zinc, or hydrogen. The counterion controls ligand exchange with hydroxyl groups, while pore size and polymer crosslinking determine the size-exclusion component. Columns in the hydrogen form additionally enable ion exclusion for organic acids. Since selectivity depends heavily on temperature, counterion, and water quality, the recommended operating conditions should be strictly adhered to.
