Trace Anion Analysis in Ultrapure Water Using an Electrolytic Water Purifier with a Compact Ion Chromatography System: Water Blank
DescriptionDeterminations of trace anions in ultrapure water are important to the electronics industry. In this record, determinations of ng/L (ppt) anions using large volume concentration are made possible by the Electrolytic Water Purifier(EWP) and AutoPrep modules. Calibration standards are prepared using the AutoPrep large and small loops and EWP-purified water diluent, thereby increasing sensitivity by eliminating sources of contamination. The trace anions are separated on an IonPac AS17-C column designed to improve low level sulfate determinations using a Dionex Integrion compact IC system.
