Calibrate suppressor regenerant water flow rate
7 Switch on the Dionex IC Pure system and start pumping of pure water
for the Dionex Integrion and Dionex ICS-2100, Dionex ICS-4000,
Dionex ICS-5000
+
, Dionex ICS-5000 or Dionex ICS-3000 system
using the Chromeleon CDS software.
8 Calibrate the suppressor regenerant water flow rate.

Note

Suppressor regenerant water flow rate must be adjusted using the flow control valve. The flow
rate should be approximately 3 to 5 mL/min for standard suppressors.

The flow rate should be determined with the suppressor connected to the suppressor supply
line of the Dionex IC Pure system and with the suppressor turned off.

The flow will be lower once the suppressor is switched on and should be checked again.
1 Record the weight of an empty container.
2 Insert the waste line from the suppressor into the container and weigh the contents after a known time interval.
3 Divide the weight of the contents of the vial (in grams) by the time to accumulate the sample. This will be the flow rate in
mL/min.
Note If external water regeneration mode will not be used, the suppressor supply connection must
be closed off. Therefore, disconnect the reducing adapter from the ‘to Suppressor‘ connection on the
Dionex IC Pure system.
Note
A few minutes is sufficient.
