This application update shows that bromate, chlorate, and
chlorite can be determined with an isocratic hydroxide
eluent to easily meet current bromate regulations. The
method was tested with mineral water, a sample that has a
higher ionic strength than most drinking water samples
and is, therefore, a good test of the method. This method
can use either a Reagent-Free™ IC (RFIC™) system or a
standard IC system. Unlike the gradient elution method in
Dionex (now part of Thermo Scientific) AN 167, this
method cannot determine all standard inorganic anions
(for example, phosphate).
