Please use this column with suppressor type ion chromatography system.

Chloric acid should be analyzed by ion chromatography for water quality standard in accordance to the Ministry of Health, Labor and Welfare in Japan. Oxyhalides and anion standards in rain water were analyzed using IC SI-52 4E. 1 mL of Ethylendiamine (EDA) solution (50 mg/mL) is to be added into 1 L sample, to prevent generation of chloric acid through the reaction between chlorous acid and residual chlorine.

Sample: 50 µL each
(Standard solution) 1 mg/L each of standard anions containing 50 mg/L of EDA
(Rain water) containing 50 mg/L of EDA
