2.1 System Requirements

The Dionex ERS 500 and Dionex ERS 500e are designed to be direct replacements for the
Dionex SRS series of suppressors, such as the Dionex SRS I, Dionex SRS II, Dionex SRS
ULTRA, Dionex SRS ULTRA II and Dionex SRS 300. The Dionex ERS 500 can be used in
place of any of these suppressors where recycled eluent mode is employed.
The Dionex ERS 500e is designed to be a direct replacement for the Dionex SRS series of
suppressors where external water mode is employed. The Dionex ERS 500e features a hardware
design that significantly improves regenerant flow when operated in external water mode.
The Dionex AERS 500 Carbonate suppressor is designed for operation with carbonate and
carbonate/bicarbonate eluents. The Dionex AERS 500 Carbonate features a hardware design
that significantly improves noise performance with carbonate eluents without sacrificing
performance or ease-of-use. The unique hardware design delivers the lowest noise level of any
electrolytic suppressor for carbonate eluents.
The Dionex ERS 500 and Dionex ERS 500e are not designed to be direct replacements for the
Dionex SRS series of suppressors where these suppressors are being used in Chemical
Suppression Mode. If Chemical Suppression Mode is being used, the Chemically Regenerated
Suppressor (Dionex CRS 500) or equivalent is recommended. The Dionex AERS 500 Carbonate
and Dionex ERS 500e can be used in the Chemical Suppression Mode; however the total
suppression capacity is reduced compared to a Chemically Regenerated Suppressor.
The Dionex ERS 500e is also designed to be a direct replacement for the Dionex SRN series of
neutralizers, such as the Dionex SRN 300, Dionex SRN-II and Dionex SRN products.
The Dionex ERS 500, Dionex ERS 500e and Dionex AERS 500 Carbonate are designed to be
run on any Dionex Ion Chromatography System (ICS) equipped with an analytical Anion or
Cation exchange column set and an electrolytic suppressor controller, such as the Thermo
Scientific Dionex ICS-5000
run on a Dionex Capillary Ion Chromatography Systems, such as the ICS-4000, or on Dionex
Ion Chromatography Systems that do not have an electrolytic suppressor controller, such as the
Dionex ICS-90A, Dionex ICS-600 or Dionex ICS-900. Some legacy systems require a
standalone controller for installation of the Dionex ERS 500, Dionex ERS 500e or Dionex
AERS 500 Carbonate. See, "Electrolytically Regenerated Suppressor Requirements for
Selected IC Modules."
The Dionex ERS control is provided by discrete (50, 100, 300, and 500mA) or non-discrete (0
to 500 mA in 1 mA increment) power supplies. Discrete Dionex ERS Control is integrated into
older systems, such as the CDM-3 and PED-2 of the Dionex DX-300, the Dionex DX-100
(Model 1-03), Dionex DX-120, Dionex DX-320 (IC20 and IC25 models), Dionex DX-500
(CD20 and ED40 detectors), and Dionex DX-600 (CD25 and ED50 detectors). The use of
discrete power supplies may not be suitable for optimal suppressor performance and may
affect the suppressor noise performance and life time.
It is therefore recommended to use a non-discrete power supply, such as the Thermo Scientific
Dionex RFC-10 or Dionex RFC-30. It is also possible to use the discrete power supplies with a
Dionex SCC-10 controller that provides twelve discrete current settings. Non-discrete Dionex
ERS Control is integrated into modern instruments, including the Dionex ICS series (excluding
Dionex ICS-90, Dionex ICS-90A, Dionex ICS-600 and Dionex ICS-900), Dionex Integrion and
Dionex Aquion.
