Avantor® Hichrom Organic Acid columns are ion exclusion columns packed with sulphonated polystyrene-divinylbenzene.

• Rapid analysis of organic acids and alcohols
• pH stable polymer resin
• Isocratic 100% aquoeus mobile phases only, no organic solvents
• USP L17

The OA-1000 and OA-2000 columns exhibit excellent selectivity for aliphatic and aromatic acids. As with most ion exclusion columns, a column heater is necessary for normal operating procedures. The IOA-1000 and IOA-2000 columns are suitable for the separation of citric and other acids from glucose and fructose.
