Dionex™ CRD 180, 200 and 300 Carbonate Removal Device

Catalog number: 062983
Improve sensitivity and increase linearity range of your ion chromatography (IC) applications by removing carbonate from the suppressed eluent stream. The Thermo Scientific™ Dionex™ CRD 180, 200 and 300 Carbonate Removal Devices support the removal of carbonate by diffusion through the walls of a carbonate-selective, gas-permeable membrane. The Dionex CRD 300 was designed for use with carbonate eluent-based chemistries, while the Dionex CRD 180 and 200 were designed for use with hydroxide- and borate-based chemistries.

Plumbed between the suppressor and detector cell, carbonate transfer is aided by a countercurrent flow of basic solution.

Dionex CRD 300 Carbonate Removal Device
  • Designed for use with carbonate eluent-based chemistries using Thermo Scientific™ Dionex™ IC columns
  • Removes carbonic acid from the suppressed carbonate eluent
  • Provides a detection system that is similar to systems using hydroxide eluents
  • Reduces the baseline for higher sensitivity
  • Increases linearity range
  • Available in two formats:
    • Dionex CRD 300 (4mm) for standard bore systems
    • Dionex CRD 300 (2mm) for microbore systems
Dionex CRD 300 can be installed in any Dionex IC system running carbonate as an eluent with a Dionex AERS 500 suppressor. The device requires either a constant flow of basic solution from a peristaltic pump or evacuation by a vacuum pump. See Dionex CRD Carbonate Removal Device Accessories for peristaltic pump and tubing. The Dionex CRD requires no reagents or software control.

Dionex CRD 180 and 200 Carbonate Removal Devices
The Dionex CRD 180 and 200 device enhances IC signals by continuously removing carbon dioxide from the sample on any Dionex™ Reagent-Free™ IC (RFIC™) system using hydr[oxide eluent.
  • Designed for use with hydroxide- and borate-based chemistries using Thermo Scientific™ Dionex™ IC columns
  • Removes the carbonate introduced from samples with high levels of dissolved carbon dioxide
  • Improves integration and quantitation of some analyte peaks that elute close to carbonate, such as such as sulfate
  • Available in several formats:
    • Dionex CRD 200 (4mm) for standard bore systems, including standard bore columns packed with 4μm resin
    • Dionex CRD 200 (2mm) for microbore systems, including microbore columns packed with 4μm resin
    • Dionex CRD 200 (Capillary) for capillary-scale systems (0.4mm columns) using flow rates of 5–30μL/min
    • Dionex CRD 180 (Capillary) is a version of the Dionex CRD 200 that has reduced internal volume and supports carbonate removal from 0.25mm and 0.4mm capillary columns
The Dionex CRD 180 and 200 device is easily installed in any Dionex RFIC system equipped with an eluent generator; a Thermo Scientific™ Dionex™ CR-ATC Continuously Regenerated Anion Trap Column; and a Thermo Scientific™ Dionex™ AERS™ 500 Anion Electrolytically Regenerated Suppressor or Dionex™ ACES™ 300 Anion Capillary Electrolytic Suppressor.
