Thermo Fisher, 075779, Dionex™ Carbonate, Methanesulfonic Acid, and Hydroxide EGC Eluent Generator Cartridges

Dionex™ Carbonate, Methanesulfonic Acid, and Hydroxide EGC Eluent Generator Cartridges is designed for automated generation of methanesulfonic acid eluent for cation-exchange ion chromatography. This exact option is the EGC 500 MSA cartridge, rather than a potassium hydroxide cartridge or an EGC III configuration. In a compatible high-pressure eluent-generator system, deionized water passes through the pumping path while the cartridge produces high-purity MSA eluent online. Automated concentration control reduces variability associated with manually preparing acid eluents and supports reproducible gradient or isocratic separations, depending on the IC method. It also reduces routine handling of concentrated acid during eluent preparation. The Dionex EGC 500 MSA format can generate up to 100 mM MSA at flow rates from 0.1 to 1.0 mL/min; the allowable concentration at higher flow rates depends on the cartridge and instrument operating conditions. The product is appropriate for compatible automated cation IC methods that specify MSA eluent.
