Shodex IC SI-35 4D (a column for rapid oxyhalides analysis) was used for the analysis of seven common anions and some organic acids. The long elution time (i.e., more than 30 minutes for succinic acid and malonic acid) required by IC SI-52 4E was shorten to 15 minutes using IC SI-35 4D. Therefore, IC SI-35 4D is also suitable for the rapid analysis of organic acids.
