AN00010: Trace Borate Determination in High-Purity Waters Be the first to rate this application


In this application note, we demonstrate and evaluate an ion-exclusion method for the determination of trace-level borate in high-purity water. This ion-exclusion method coupled with suppressed conductivity detection offers an integrated solution. We used a Dionex™ IonPac™ ICE-Borate analytical column and a Dionex™ IonPac™ TBC-1 Trace Borate concentrator column, specifically designed for this application. The experimental approach shown combines large sample volume/preconcentration with ion exclusion chromatography. This approach achieves sensitive detection at low to sub-μg/L levels.
