C.4.2 Home Page EGC Controls
The
EGC
controls indicate the
type and the eluent
concentration of each installed
EluGen Cartridge (EGC). The
CR-TC
field indicates whether
the Continuously Regenerated
Trap Column is on or off.
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). When the ICS-2000 is controlled from the front panel, only
isocratic eluent delivery is possible. With isocratic delivery, the eluent
composition and concentration remain constant throughout the run. When the
ICS-2000 is under Chromeleon control, gradient delivery, in which the eluent
concentration changes over time, is also possible.
To set the eluent concentration or to turn on or off the CR-TC, touch the
concentration button. The
ELUENT GENERATOR
page appears (see Section C.8 ).
C.4.3 Home Page Column Heater
The temperature of the column heater can be controlled to
between 30 and 60 °C. For optimal performance, set the
column heater to at least 5 °C above the ambient
temperature. To set the temperature, touch the
Column
Heater
field and enter the desired temperature on the number pad. To turn the
column heater off, set the temperature to 0. The display to the right of the
temperature setting indicates the heater status:
= column temperature is at equilibrium
↑
column temperature is rising
↓
column temperature is falling
Off column heater is off
