SUGAR KS-2005 300x20mm Sugar Preparative Column

The SUGAR KS-2005 HPLC column 300x20mm, 25µm, is a preparative version packed with a sulfonated styrene-divinylbenzene resin and sulfonic acid groups in sodium form. SUGAR KS-2005 adopts the very wide-pore selectivity of the analytical KS-805 and achieves a nominal exclusion limit of about 5,000,000 Da for pullulan. The column is designed for the preparative fractionation of high-molecular-weight polysaccharides and other water-soluble macromolecules.

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.
