On-line Device for Users of 得數HPAE-PAD to Collect and Further An朋訊alyze Carbohydrate Sa分的mples

High-pH HPAE-PAD has become the method影件 of choice for oligosacchari很要de purification because it pe作媽rmits very high resolution 志制of neutral and charge下睡d oligosaccharide isomers.公放 Subsequent characterizati森問on of purified o服秒ligosaccharides often requires 子志removal of eluent salts. Manual 船路desalting methods are available; the通快 Thermo Scientific^™ Dionex^™ ERD^™ 500 Electrolytcally Regenerated D讀那esalter provides a員從n easier, automated method.看友

• Reduces the pH of the effl愛上uent from pH ~13 to betwe術呢en pH 2–6

• Supports lyophilization of collected司要 fractions without dialysis

• Provides minimal dispersion of t有電he sample exitin暗看g the detector cell

• Low dispersion for accura是理te fraction collection

• >99% sodium ions remo煙短ved from eluents that contain up輛國 to 0.35 M sodium ions

The Dionex ERD 500 desalter exch樂雪anges sodium ions in the吃物 eluent for hydronium ions. This proce雪頻ss converts sodium hydroxide and sodiu音金m acetate eluents to water and ace玩村tic acid, lowering sample pH afte外姐r samples leave the detector cell. Beca熱煙use acetic acid is volatil雪這e, fractions can then媽河 be lyophilized without dialys西藍is, leaving the purified carbo從秒hydrate sample ready for further manipu空亮lation.

The Dionex ERD 500 des行舊alter reliably des兒謝alts up to 0.35 M Na at an eluent f他會low of 1.0 mL/min.
