A suppressed ion chromatography (IC) technique, using a carbonate/hy- drogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F - ,C l - ,N O3 - ,P O4 3- and SO4 2- ) in ultra pure water and condensed steam from thermal power plants. An electrical conductivity detector with an anion-exchange column (IonPac AS14), an auto self-regenerating suppres- sor (ASRS), and an isocratic high-pressure pump system were used for the detection of low concentrations of inorganic anions. It was shown that the suppressed IC tech- nique provides a suitable means for preventing possible damage to generating equipment in power plants. The detection limits of the method for the anions of in- terest were < 0.3 g/L.
