2.4.4 Eluent Generator
The eluent generator produces high-purity eluents online, using only
deionized water as the carrier. The eluent generator consists of an eluent
generator cartridge (EGC) that generates the eluent, and a high-pressure
degas tubing assembly that removes electrolysis gases created during
eluent generation.
NOTE A gas separator waste tube (P/N 045460) should
be connected to the system waste line during
installation (see Section B.10.1
).
Several types of EluGen cartridges are available for use with the ICS-
2100 (see Table 2-1)
. Each cartridge contains 900 mL of the appropriate
electrolyte concentrate solution for eluent generation.
For more information, refer to the EluGen cartridge manual. The manual
is included on the Dionex Reference Library CD-ROM (P/N 053891).
