Bromate in Drinking Water

Please use this column with suppressor type ion chromatography system.

Recently ozonation has been applied for sterilization of drinking water. Ozonation transforms part of bromide to bromate which is a potential carcinogen. So, it is very important to measure bromate in drinking water. A modeldrinking water with bromate was measured by suppressed coductivity with IC SI-50 4E.
