Linked Dual-Cartridge Configuration
In the linked dual-cartridge configuration, the EG contains two EluGen cartridges,
linked to a single pump, that perform as one cartridge. Note that the allowable
eluent concentration for a linked cartridge is less than when the cartridge is
defined as independent. For details, refer to the EluGen cartridge manual.
Cartridge manuals are included on the Dionex Reference Library CD-ROM
(P/N 053891).
Notes for Generating Carbonate/Bicarbonate Eluent
If a K

EluGen cartridge and an EPM Electrolytic pH Modifier are installed
(EGC_1 and EGC_2, respectively), set EGC_1 Target Concentration to the
concentration of K

required for your application and set EGC_2 Target
Concentration to the concentration of KHCO
