RFIC Eluent Degasser
For analytical IC systems, an RFIC Eluent Degasser (P/N 062137) is installed
on the EG component mounting panel. The degasser contains a tubing
assembly that purges the electrolysis gas from the freshly-generated eluent
before it is directed to the separator column.
For capillary IC systems, the degasser is installed in the IC Cube (see
Section 2.11.2 ).
Backpressure Coil (Optional)
For analytical IC systems, the EGC requires at least 14 MPa (2000 psi) of
system backpressure for removal of electrolysis gas from the eluent produced
by the cartridge. A system backpressure of 16 MPa (2300 psi) is ideal.
If necessary, increase the system backpressure by installing a backpressure
coil between the injection valve and the EGC
OUTLET
port. For details, refer
to Section 9.17 .
EPM III Electrolytic pH Modifier and Carbonate Mixer
The EGC III K

can be used with an EPM III Electrolytic pH Modifier
(P/N 080135) and a carbonate mixer (P/N 061686, 4 mm; P/N 063443, 2 mm)
to produce a carbonate/bicarbonate mixture for use with anion exchange
separations on carbonate-based Dionex IonPac columns.
After the cartridge generates potassium carbonate eluent, the EPM adjusts the
eluent concentration to produce the carbonate/bicarbonate mixture. The
carbonate mixer provides mixing necessary to produce a homogenous
solution of electrolytically-generated K

eluent.

manuals are included on the Thermo Scientific Reference Library DVD
(P/N 053891).
Leak Sensor
If liquid collects in the drip tray in the bottom of the EG, a leak sensor reports
the leak to Chromeleon, and an error message is displayed in the Audit Trail.
In addition, the

LED on the EG front panel lights.
