Elution Behavior of Organic Acids in Donnan Exclusion Chromatography

摘要

The elution behavior of organic acids has been elucidated using a dextran gel-type cation-exchanger column with an eluent of 1.00 M tetramethylammonium chloride. It was found that Donnan exclusion chromatography is applicable to organic acids as well as inorganic ones. Some types of separation methods were performed by the use of the separation mode whose mechanism was confirmed by Donnan exclusion chromatography.
