EGC calibration error
EGC disconnected error
EGC invalid concentration vs. flow rate
Thermo Scientific
This error occurs when the measured current during the Dionex EGC calibration procedure is
outside the expected range. (Note that the calibration procedure must be performed by
Thermo Fisher Scientific personnel.)
To troubleshoot

1. Review the calibration procedure to verify that the Dionex Aquion RFIC was set up
correctly.
2. Run the calibration again.
This error occurs if the Dionex EGC is disconnected from the Dionex Aquion RFIC at the
following times:
• When Chromeleon is attempting to send a Dionex EGC-related command to the system.
• When the Dionex EGC verification test is in progress. (Note that the verification test
must be performed by Thermo Fisher Scientific personnel.)
To troubleshoot

1. Verify that the Dionex EGC cable is securely connected to the
Dionex Aquion RFIC top cover (see
2. If the error message appears again, it may indicate a malfunction in the Dionex EGC
control electronics. Contact Technical Support for Dionex products for assistance.
Note Dionex Aquion RFIC electronics components cannot be serviced by the user.
This error occurs when the selected eluent concentration is too high for the current flow rate.
The maximum eluent concentration for a particular application depends on the suppressor
type, the Dionex EGC type, and the flow rate.
To troubleshoot

1. Refer to the column manual for the recommended parameters for your application.
2. Reset the eluent concentration and/or the flow rate to the recommended values.
