Dionex SRD-10 Suppressor Regenerant Detector

The Dionex SRD-10 Suppressor Regenerant Detector is a stand-alone device that monitors
liquid flow to a suppressor. If the flow is restricted or stops, the Dionex SRD-10 automatically
disables the eluent pump via a TTL command, thus preventing irreversible damage being done
to the suppressor. In the external water mode, if the water runs out in the source reservoir then
the suppressor would be powered without any regenerant flow;
irreversible damage to the suppressor. Installing the Dionex SRD-10 suppressor regenerant
detector avoids this issue, as the system is turned off if the regenerant flow is interrupted either
due to a plumbing leak or due to the source reservoir becoming empty.

3.5 Plumbing for Chemical Suppression Mode Operation

The Dionex ERS 500 is not compatible with the chemical suppression mode. Therefore Thermo
Scientific Dionex recommends the Dionex CRS 500 or equivalent for chemical suppression
mode applications.
The Dionex ERS 500e and Dionex AERS 500 Carbonate can be used in the Chemical
Suppression Mode; however the total suppression capacity is reduced compared to a Chemically
Regenerated Suppressor. Thermo Scientific recommends the use of a Chemically Regenerated
Suppressor such as the Dionex CRS 500 for chemical suppression applications.
!
The Dionex ERS 500 is not compatible with the Chemical Suppression Mode. The Dionex
CRS 500 or equivalent should be used when Chemical Suppression Mode is required.
NOTE

3.6 Plumbing for MPIC Suppression Mode of Operation

The Dionex AERS 500e can be used with current applied to the suppressor augmented by dilute
sulfuric acid in the regenerant solution. If you intend to use an AutoRegen Accessory, configure
the system as described in
Mode Operation," and use the appropriate sulfuric acid concentration instead of water. The
Dionex CERS 500e can be used with current applied to the suppressor augmented by diluted
boric acid in the regenerant solution.
!
The following installation instructions are based on a system configured with a pressurized
water delivery system, but apply equally well to peristaltic pump delivery systems.
NOTE
!
The Dionex ERS 500 suppressor is not recommended for use with the MPIC Suppression
Mode of Operation. The Dionex ERS 500e should be used.
