Analysis of Oxyhalides and Anion Standards (SI-52 4E)

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 were analyzed using Shodex IC
SI-52 4E 1mL of Ethylendiamine (EDA) solution (50mg/mL)
is to be added into 1L sample, to prevent generation of chloric acid through the reaction between chlorous acid and residual chlorine.
