Advances in Bromine Speciation by HPLC/ICP-MS

This application note demonstrates a rapid, robust method for separating and measuring bromide and bromate in drinking waters. The separations are accomplished in less than three minutes and prove to be repeatable from injection to injection and over several days. For those waters containing additional bromine-containing species, a gradient HPLC method was established. Taken together, the isocratic separation scheme can serve as a rapid screening method; those samples which contain additional bromine species can then be analyzed by the longer gradient method.
