SUGAR KS-804, 8.0 x 300 mm, HPLC column

The SUGAR KS-804 HPLC column 300x8.0mm, 7µm, whose packing material consists of a sulphonated styrene-divinylbenzene resin with sulfonic acid groups in the sodium form. Separation is based, depending on the counter-ion, on ligand exchange, ion exclusion and size exclusion. The wide-pore packing addresses large hydrodynamic volumes. The nominal separation range is approximately 1,000 to 400,000 Da. Typical application areas for SUGAR KS-804 are polysaccharides and higher molecular weight carbohydrates.

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.
