Calibration Curves for Oxyhalides (SI-52 4E)

Please use this column with suppressor type ion chromatography system.

By use of IC SI-52 4E, even trace level (5ppb) of oxyhalides, such as chlorite (ClO₂^-), bromate (BrO₃^-) and chlorate (ClO₃^-), can be determined simultaneously with seven common inorganic anions. Each calibration curve shows very good linearity over the wide range of concentration.
