The carbon dioxide removal device is installed between the suppressor and conductivity detector. Carbonates from the sample in the hydroxide system can interfere with the analysis of anions, such as sulfates. Under these conditions, using a carbon dioxide removal device to minimize carbonates can improve the integration and quantification of target anion peaks .
