Dionex CERS 500e - Cation Electrolytic Suppressor for Ion Chromatography

The Dionex CERS 500e (Cation Electrolytic Regenerating Suppressor) is a self-regenerating electrolytic suppressor for cation ion chromatography. It converts the eluent (methanesulfonic acid or MSA) to weakly conductive water and methanol, enabling high-sensitivity suppressed conductivity detection of cations.

Key Specifications:

• Manufacturer: Thermo Scientific (Dionex)
• Type: Cation electrolytic self-regenerating suppressor
• Compatible Columns: IonPac CS12A, CS16, CS19
• Eluent Compatibility: Methanesulfonic acid (MSA)
• Regenerant: Electrolytically generated — no external chemical regenerant needed
• Format: 2 mm and 4 mm
• Part Number: 302663

Why Choose the CERS 500e?

The CERS 500e eliminates the need for external chemical regenerant solutions, reducing operating costs and simplifying system maintenance. The suppressor continuously regenerates electrolytically during operation, providing stable suppression with no downtime for regeneration cycles.

This self-regenerating design ensures consistent baseline stability, low detection limits, and reliable performance for high-throughput cation analysis.

Applications:

• Drinking water cation profiling (Li⁺, Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺)
• Pharmaceutical raw material testing
• Environmental cation monitoring
• Food and beverage mineral analysis
• Power plant water chemistry

System Compatibility:

Designed for Dionex ICS-series systems. Use with IonPac CS12A or CS16 analytical columns and CG12A or CG16 guard columns for complete cation analysis systems.
