Ion Chromatography

Shodex™ ion chromatography columns are among the best in the industry. We offer both suppressed columns for sensitive anion separations required for water analyses and non-suppressed columns that can be run on traditional HPLC systems equipped with a conductivity detector. Refer to the features for each column and the column selection guide below.
