TN72206: Configuring the Dionex Modular HPIC System with an Inline Water Purifier and Inline Calibration for Trace Anion Determinations in Ultrapure Water: EWP Water Blank

Instrument Type: IC

In the electronics industry, ionic contamination in the range of parts per trillion (ppt, ng/L) to parts per billion (ppb) concentrations is a major concern, causing corrosion-related failures in production and final product. Ionic contamination is increasingly important as the devices decrease to size. This technical note demonstrates automated calibration and water purification on an ICS-5000+ HPIC dual IC system to minimize the system and environmental contamination which resulted in increased sensitivity to double-digit-ppt concentrations. An ICS-6000 can be used for this application.

TN72206: Configuring the Dionex Modular HPIC System with an Inline Water Purifier and Inline Calibration for Trace Anion Determinations in Ultrapure Water: 50 ppt Standard

Instrument Type: IC

In the electronics industry, ionic contamination, in the range of parts per trillion (ppt, ng/L) to parts per billion (ppb) concentrations, is a major concern causing corrosion-related failures in production and as a product. Ionic contamination is increasingly important as the devices decrease to size. This technical note demonstrates automated calibration and water purification on an ICS-5000+ HPIC dual IC system to minimize the system and environmental contamination which resulted in increased sensitivity to double-digit-ppt concentrations. An ICS-6000 can be used for this application.

Trace Anion Analysis in Ultrapure Water Using an Electrolytic Water Purifier with a Compact Ion Chromatography System: Water Blank

Instrument Type: IC

Determinations 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.
