概要

• 論文の詳細を見る

• Ion-exclusion chromatographic separation of organic acids using a carbonic acid solution as eluent is presented. This permits conductivity detection of ionic species without a suppressor as a post-column reactor. It was found that the proposed method was applicable to the separation of organic acids having p<I>K</I><SUB>a</SUB> over <I>ca</I> 3.5. This technique was applied to the determination of acetic acid in pharmaceuticals without tedious sample preparation.
