Dionex CDRS 600 - Chemical Suppressor for Carbonate-Based Ion Chromatography

The Dionex CDRS 600 (Chemical Desalting Reagent-free Suppressor) is a chemical-mode suppressor designed for anion IC systems that use carbonate/bicarbonate eluent. It converts the eluent to weakly conductive carbonic acid, reducing background conductivity and enabling sensitive suppressed conductivity detection of anions.

Key Specifications:

• Manufacturer: Thermo Scientific (Dionex)
• Type: Chemical-mode suppressor
• Application: Anion analysis with carbonate/bicarbonate eluent
• Compatible Eluents: Sodium carbonate/bicarbonate mixtures
• Format: 2 mm and 4 mm

Why Use the CDRS 600?

The CDRS 600 provides effective suppression for IC systems that use manually prepared carbonate/bicarbonate eluents (non-electrolytic systems). It delivers stable, low-noise baselines essential for trace-level anion detection.

For laboratories running the IonPac AS22 or AS14A columns with carbonate eluent, the CDRS 600 is the recommended suppressor for reliable day-to-day operation.

Applications:

• Routine drinking water anion analysis
• Environmental compliance testing
• Industrial water quality monitoring
• Any carbonate-eluent IC application

System Compatibility:

Compatible with Dionex ICS-series systems including ICS-2100, ICS-5000+, and Aquion. Pair with IonPac AS22 or AS14A columns for optimal performance.
