SUNNYVALE, Calif. (Oct 2011) — Thermo Fisher Scientific Inc. is pleased to announce a new application demonstrating the separation of common inorganic anions and cations in municipal drinking water samples on the capillary Thermo Scientific Dionex IonPac AS19 hydroxide-selective anion-exchange column and the Thermo Scientific Dionex IonPac CS12A columns using electrolytically generated eluent. The analytes were detected by suppressed conductivity using the Thermo Scientific Dionex Capillary Electrolytic Suppressors (CESTM) and the capillary Thermo Scientific Dionex ICS-5000 Reagent-Free IC (RFICTM) IC system.

Application Brief 133, Cost-effective Determination of Inorganic Anions and Cations in Municipal Drinking Water using Capillary Ion Chromatography, should be of interest to municipal water companies and other companies determining inorganic anions and cations in simple-matrix environmental samples. Capillary IC systems can be left on and ready for analysis at any time, maintaining stability and requiring less frequent calibrations, thus reducing analysis time and increasing throughput. The amount of waste generated is significantly decreased and the eluent generation cartridge producing the eluent lasts 18 months under continuous operation mode, reducing overall cost of ownership.
