The Dionex DRS 600, Dionex ERS 500e and Dionex AERS 500 Carbonate suppressors are designed for different applications. See the following table for details.

Suppressor models and suitable applications

Suppressor model

Suitable applications

Compatible ion chromatography system (ICS)

Dionex DRS 600

Direct replacement for:

  • Dionex ERS 500 suppressor
  • Dionex SRS series suppressors1) (Dionex SRS I, Dionex SRS II, Dionex SRS ULTRA, Dionex SRS ULTRA II and Dionex SRS 300)
  • Dionex SRN series neutralizers (Dionex SRN 300, Dionex SRN-II and Dionex SRN)

Can be used in place of any of these suppressors where recycled eluent mode or external water mode is employed.

Any Dionex Ion Chromatography System (ICS) equipped with an analytical Anion or Cation exchange column set and an electrolytic suppressor controller, including:

  • Thermo Scientific Dionex ICS-6000
  • Dionex Integrion
  • Dionex Aquion

NOTE: Some legacy systems require a standalone controller for installation. See Electrolytically regenerated suppressor control.

Dionex ERS 500e

External water applications where difficult sample matrices are being analyzed.

Dionex AERS 500 Carbonate suppressor

Operation with carbonate and carbonate/bicarbonate eluents. Hardware design significantly improves noise performance with carbonate eluents without sacrificing performance or ease-of-use and delivers the lowest noise level of any electrolytic suppressor for carbonate eluents.

Dionex CRS 500
(or equivalent)

Chemical suppression mode.

CAUTION

The Dionex DRS 600, Dionex ERS 500e and Dionex AERS 500 Carbonate suppressors are not designed to be run on Dionex Capillary Ion Chromatography Systems (ICS-4000), or on Dionex Ion Chromatography Systems that do not have an electrolytic suppressor controller (Dionex ICS-90A, Dionex ICS-600, Dionex ICS-900).
