Demonstrates the determination of inorganic anions in drinking water by IC with built-in peristaltic pump for regenerant flow to a chemical suppressor.
This work demonstrates a five-minute analysis method to determine inorganic anions in drkinking water by an integrated, single-channel compact IC.
The method used a Thermo Scientific™ Dionex™ IonPac™ AS23-4μm column, a Thermo Scientific™ Dionex™ AERS™ 500 Carbonate anion electrolytically regenerated suppressor, and a Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device in vacuum mode. This work demonstrates a similar method on a Thermo Scientific™ Dionex™ Inuvion™ ion chromatography system, a new integrated, single-channel compact IC system.
This application proof note demonstrates a method for the determination of inorganic anions in municipal drinking water, which is based on the method published in Thermo Fisher Scientific Application Update 200. In this proof note, the method is performed using a new, innovative IC system that uses an electrolytic eluent generator to automatically produce eluent.
Denatured ethanol is a popular substitute for petroleum fuels. It is important to determine the chloride and sulfate concentrations and to determine the concentration of sulfur ions that could be oxidized to sulfate (potential sulfate). This application was previously demonstrated on AU72996. The same application is demonstrated on 4 × 250 mm, Dionex IonPac AS22 anion-exchange column using manually prepared carbonate eluent with the suppressor upgraded to current technology. The application is facilitated by a Thermo Scientific™ Dionex™ Inuvion™ IC system.
