AN113: Determination of Trace Anions in High Purity Waters by High Volume/Direct Injection Ion Chromatography
Description
Trace anion determinations are important to the power and the electronics industries. The Electric Power Research Institute (EPRI) recommends using IC to determine concentrations down to 0.25 µg/L, whereas the Semiconductor Equipment and Materials International (SEMI) recommend IC for contaminants from 0.025 to 0.5 µg/L. This application note describes the use of a gradient separation using the IonPac AS11 column for the determination of trace anions by high volume/direct injection. This method is applicable to pure water samples and high-purity waters containing corrosion inhibitors.| Market: | Water Analysis |
