ABSTRACT
Tanaka and Fritz1 have described a procedure for the determination of bicarbonate and carbon dioxide in water by ion-exclusion chromatography using water as the eluent and an electrical conductivity detector. The sensitivity of detection is improved approximately 10 fold by the use of two ion exchange enhancement columns inserted in series between the separating column and the detector. The first enhancement column converts carbonic acid to potassium bicarbonate and the second enhancement column converts the potassium bicarbonate to potassium hydroxide.
