SUGAR KS-2003 300x20mm Sugar Preparative Column

The SUGAR KS-2003 300x20mm, 20µm, 300x20mm, 20µm, is based on a sulfonated styrene-divinylbenzene resin with sulfonic acid groups in sodium form. SUGAR KS-2003 transfers the medium pore structure of KS-803 to higher sample amounts and has a nominal exclusion limit of about 50,000 Da for pullulan. Typical applications are the preparative separation of oligosaccharides and smaller polysaccharides.

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.
