If the ICS-2100 is not under Chromeleon control, enter the cartridge serial
number by touching the
Serial Number field on the ELUENT GENERATOR
page (see Figure B-16
) and entering the serial number on the keypad.
If you are reinstalling a cartridge that was used previously, touch the
down arrow instead of the number field. A list of the last five entered
serial numbers drops down. Choose the serial number of the cartridge
from the list.
NOTE When the EGC-2 power supply is configured as an
auxiliary power supply, the EGC-2 Serial Number
field displays
None.
B.8.2 Setting the Eluent Concentration
To set the concentration of eluent to be generated, touch the Setpoint
field and enter the concentration on the keypad. If the ICS-2100 power is
turned off, the setpoint value is restored when the power is turned on
again.The
Actual Concentration field displays the concentration of
eluent currently being generated.
The suppressor type, EGC type, and flow rate determine the maximum
eluent concentration for a particular application. To determine the eluent
concentration for your application, refer to the column manual. Column
manuals are included on the Dionex Reference Library CD-ROM
(P/N 053891).
If a K
2
CO
3
EluGen cartridge and an EPM Electrolytic pH Modifier are
installed (connected to EGC-1 and EGC-2, respectively), set EGC-1 to
the concentration of K
2
CO
3
required for your application and set EGC-2
to the concentration of KHCO
3
required. When the eluent is generated,
the
EGC-1 Actual Concentration field displays the total of the two
setpoint concentrations. This is the actual concentration of K
2
CO
3
that the
cartridge must generate in order to achieve the desired K
2
CO
3
/KHCO
3
eluent mixture.
For example, for a 3.50 mM K
2
CO
3
/1.00 mM KHCO
3
eluent, set EGC-1
to 3.50 mM and EGC-2 to 1.00 mM. When the eluent is generated, the
EGC-1 Actual Concentration field will display 4.50 mM.
