Thermo Fisher, 075778, Dionex™ Carbonate, Methanesulfonic Acid, and Hydroxide EGC Eluent Generator Cartridges

Dionex™ Carbonate, Methanesulfonic Acid, and Hydroxide EGC Eluent Generator Cartridges is designed for online production of potassium hydroxide eluent in reagent-free ion chromatography. The cartridge forms part of a compatible Dionex eluent generation system that uses deionized water as the feed and electrical current to control the generated KOH concentration. It supports anion-exchange methods requiring reproducible hydroxide eluent, including hydroxide-gradient operation without manually mixing concentrated base solutions for each run. The device is the EGC 500 potassium hydroxide version, not the methanesulfonic acid or potassium carbonate cartridge available within the same product family. With a compatible system, it generates up to 100 mM eluent at 0.1–1.0 mL/min. At higher flows up to 3.0 mL/min, its maximum permitted concentration decreases as a function of the instrument's current and flow limits. The eluent generation process also requires the appropriate high-pressure degassing arrangement to remove electrolysis gases. The cartridge is a consumable for analytical eluent production and is not a prefilled bottle of KOH mobile phase.
