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.

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.

TN48 (Method 2): Determination of Trace Anions in High-Purity Water by High-Volume Direct Injection with Online Eluent Generation

Instrument Type: IC

This note describes the use of the eluent generator with the high-volume direct-injection technique to determine trace anions in high-purity waters. The ability to generate high-purity and carbonate-free eluents on-line improves performance for trace-level analysis. Retention time reproducibility is improved, especially for early-eluting species. The baseline shift from the hydroxide gradient is significantly reduced. Two columns are described: the 2-mm IonPac AS11 & 2-mm AS15. Common inorganic anions and low molecular weight organic acids are determined below μg/L levels in less than 35 min.
