Analysis of Oxyhalides (SI-52 4E)

Please use this column with suppressor type ion chromatography system.

Recently ozonation has been applied for disinfection of drinking water. Ozonation transforms a part of bromide (Br) to bromate (BrO3), which is a potential carcinogen. Therefore, it is important to measure bromate in drinking water. IC SI-52 4E can analyze common inorganic anions and oxyhalides simultaneously with high resolution. Dichloroacetate (DCA) as a surrogate substance is also well separated. Water dip and carbonate system peak do not overlap with other peaks.
