SUGAR KS-805 300x8mm Sugars

The SUGAR KS-805 HPLC column 300x8.0mm, 17µm, is based on a sulfonated styrene-divinylbenzene resin with sulfonic acid groups in sodium form. The wide-pore polymer matrix extends the size-exclusion range considerably beyond KS-804. For SUGAR KS-805 the nominal exclusion limit is about 5,000,000 Da for pullulan. Typical application areas are high-molecular-weight polysaccharides and other water-soluble macromolecules; water or a suitable aqueous eluent is used as the mobile phase.

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.
