SUGAR SH1821, 8.0 x 300 mm, HPLC column

The SUGAR SH1821 HPLC column 300x8.0mm, 6µm, is based on a sulfonated styrene-divinylbenzene resin with sulfonic acid groups in the hydrogen form. Separation is based, depending on the counter‑ion, on ligand exchange, ion exclusion and size exclusion. The expanded pore structure supports larger acidic carbohydrates and oligomers. The nominal separation range is approximately 500 to 10,000 Da. Typical application areas of SUGAR SH1821 are uronic acids, aldonic acids and 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.
