EG Routine Maintenance
This section describes routine maintenance procedures for the ICS-3000 Eluent
Generator (EG) that users may perform. All other maintenance procedures must
be performed by Dionex personnel.
For information about maintenance procedures for the EluGen cartridge, CR-TC
trap column, or suppressor, refer to the appropriate product manual. These
manuals are included on the Dionex Reference Library CD-ROM (P/N 053891).
7.6 EG Daily Maintenance
• Locate and repair leaks inside the EG (see Section 9.11) and wipe up liquid.
Rinse dried eluents off components with deionized water.
• Rinse the EG drip tray with deionized water (to prevent formation of salt
crystals) and dry the drip tray thoroughly. Rinse and dry the leak sensor, also;
if the sensor is not dry, it will remain activated and continue to report a leak to
the Audit Trail.
• Check the waste container and empty as needed.

7.7 EG Weekly Maintenance
• Check all air and liquid lines for crimping. Move (or reroute) pinched lines
and replace damaged lines (see Section 9.10
). For help in isolating the cause
of a tubing restriction, see Section 9.11
.
• Monitor the system backpressure. A gradual increase in backpressure can
indicate clogging of the EluGen cartridge inlet frit from particulates in the
eluent water.
7.8 EG Annual Maintenance
• Check the expiration date and remaining lifetime of the EluGen cartridge on
the EG Control panel in Chromeleon or Chromeleon Xpress.
