Eluent Generation—A Major Component of Reagent-Free IC
Eluent generation prevents baseline shift, increases sensitivity, improves resolution, and ensures consistent peak integration. Dionex offers a range of EGC cartridges for the production of hydroxide, carbonate, and methanesulfonic acid eluents. Eluent generation eliminates the need to handle acids and bases traditionally required for the preparation of IC eluents, and allows chromatographers to run a full range of gradient and isocratic separations more effectively than hand-made eluents.
Automatic production of high-purity eluents for isocratic and gradient runs on ICS-5000 and ICS-2100 systems
Outstanding run-to-run reproducibility week after week
Elimination of acid and base handling
Longer lasting pumps because they encounter only deionized water
Supports both Analytical and Capillary flow rates
Electrolytic Eluent Generation Process
EGC cartridges support a concentration range of 0.1–100 mM (0.1–80 mM EGC-LiOH) at 1.0 mL/min. The KOH, NaOH and LiOH cartridges support a maximum of 25% methanol. The potassium carbonate and MSA cartridges are not solvent-compatible.
EGC-Capillary cartridges support a concentration range of 0.1–200 mM at 0.010 mL/min and a flow rate range of 0.001–0.030 mL/min. The EGC-KOH (Capillary) cartridge supports a maximum of 25% methanol. The EGC-MSA (Capillary) cartridge is not solvent-compatible.
