Determination of Organic Acids in Wastewater Using Ion-Exclusion Chromatography and On-Line Carbonate Removal

This study by Dionex shows a method for determining organic acids in wastewater using ion-exclusion chromatography and on-line carbonate removal. Inorganic anions are eluted in the void volume and the Dionex CRD 200 removes carbonate on line. The results show that this combination allows the accurate determination of organic acids in a wastewater sample.
