WebQuestion: Detection limit. A sensitive chromatographic method was developed to measure sub-part-per-billion levels of the disinfectant by-products iodate (IO23), chlorite (ClO2), and bromate (BrO23) in drinking water. As the oxyhalides emerge from the column, they react with Br2 to make Br23, which is measured by its strong absorption at 267 nm. http://lacc-terryb.com/files/Formal-Lab-Report_Expt-2-sample2B.pdf
