The connection between the suppressor and detector cells enables self-transfer of carbonic acid by countercurrent flow of alkaline solution.

Dionex CRD 300 Carbonate Removal Device
  • Intended for use with carbonate eluent chemistries using Thermo Scientific™ Dionex™ IC columns< /li>
  • Removes carbonic acid from suppressed carbonate eluents
  • Provides a detection system similar to those using hydroxide eluents
  • Lowers the baseline to Get higher sensitivity
  • Increase linear range
  • Available in two sizes:
    • Dionex CRD 300 (4mm) for standard bore systems
    • Dionex CRD 300 (2mm) for microbore systems
Dionex CRD 300 can be installed in any system using carbonate as eluent, Dionex AERS 500 in a Dionex IC system operating as a suppressor. The equipment requires a peristaltic pump to stably pump the alkaline solution or a vacuum pump to evacuate. See Dionex CRD Carbonate Removal Device Accessories for Peristaltic Pumps and Catheters. Dionex CRD requires no reagents or software control.

Dionex CRD 180 and 200 Carbonate Removal Devices
The Dionex CRD 180 and 200 devices use a hydroxide eluent to continuously remove any Dionex™ Reagent-Free™ IC ( RFIC™) system to enhance the IC signal.
  • Intended for use with hydroxide and borate chemistries using Thermo Scientific™ Dionex™ IC columns
  • Removes carbonates introduced from samples containing high concentrations of dissolved carbon dioxide< /li>
  • Improve integration and quantification of some analyte peaks that elute close to carbonate (e.g. sulfate)
  • Available in various formats:
    • For use in standard well systems Dionex CRD 200 (4mm), including standard pore columns filled with 4µm resin
    • Dionex CRD 200 (2mm) for micropore systems, including micropore columns filled with 4µm resin
    • Dionex CRD 200 (capillary type), suitable for capillary-grade systems (0.4mm columns) using flow rates of 5–30 μL/min
    • Dionex CRD 180 (capillary type) is a model of Dionex CRD 200, It reduces internal volume and supports carbonate removal from capillary columns from 0.25mm to 0.4mm
Dionex CRD 180 and 200 units can be easily installed in On any Dionex RFIC system with accessories: eluent generator; Thermo Scientific™ Dionex™ CR-ATC continuously regenerated anion trap column; Thermo Scientific™ Dionex™ AERS™ 500 Anion Electrolysis Regeneration Suppressor or Dionex™ ACES™ 300 Anion Capillary Electrolysis Suppressor.
