SUGAR KS-2002 300x20mm Ion Exchange Preparative Column

The SUGAR KS-2001 HPLC column 300x20mm, 20µm, is a preparative version packed with a sulfonated styrene-divinylbenzene resin and sulfonic acid groups in sodium form. SUGAR KS-2001 transfers the small-pore structure and selectivity of the analytical KS-801 to a preparative format; the nominal exclusion limit is about 1,000 Da for pullulan. The larger bed capacity supports higher sample loadings and fraction collection of mono- and disaccharides as well as small oligosaccharides.

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.
