Calibration Curves for Oxyhalides (SI-52 4E)

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.
