Thermo Fisher, 085087, Dionex™ ERD™ 500 Electrolytically Regenerated Desalter

Description: 4 mm Dionex ERD 500
Unit Size: Each 1
Automate Salt Removal and pH Reduction for Oligosaccharide Separations The Dionex ERD 500 Electrolytically Regenerated Desalter lowers sample pH and removes move than 99% of sodium ions by exchanging sodium for hydronium ions, thus converting sodium hydroxide and sodium acetate eluents to water and acetic acid. The volatile acetic acid makes it possible to lyophilize fractions without dialysis, leaving the purified carbohydrae sample ready for further manipulatin.
• Reduces effluent pH from ∼13 to 2-6
• Saves in laborious lyophilization of collected fractions without dialysis
• Removes greater than 99% of sodium ions from eluents containing up to 0.35 M Na+
• Maximizes dispersion of the sample exiting the detector cell for accurate fraction collection
• Provides continuous desalter regeneration using electolysis and trifluoroacetic acid (TFA) regenerant
