Lower Baseline Conductivity

The CES 300 Capillary Electrolytic Suppressor lowers baseline conductivity for anion (Thermo Scientific™ Dionex™ ACES™ 300 Capillary Electrolytic Suppressor) and cation (Thermo Scientific™ Dionex™ CCES™ 300 Capillary Electrolytic Suppressor) detection by converting highly conductive hydroxide or methanesulfonic acid eluents into pure water. It simultaneously boosts sensitivity for conductivity detection by converting analytes into their more conductive hydronium (anion) or hydroxide (cation) forms for a significant increase in signal-to-noise ratio.

Easy to Use Noise Reduction for Capillary Ion Chromatography

• Reduced baseline conductivity
• Enhanced sensitivity for conductivity detection
• Optimized for capillary flow rates (5–30µL/min)
• Time-saving electrolytic regeneration; no need to mix reagents
• Minimal dead volume with high suppression capacity due to three-chamber design

Flexible Operating Modes

• Water-saving “Recycle Mode” recommended for aqueous eluents
• Powerful “External Water Mode” recommended for eluents containing solvent and samples with high solvent or transition metal content
