2.4.6 Column Heater
2.4.7 Suppressor
The suppressor reduces the eluent conductivity and enhances the
conductivity of the sample ions, thereby increasing detection sensitivity.
Either an Atlas Electrolytic Suppressor, Self-Regenerating Suppressor, or
MicroMembrane Suppressor can be used with the ICS-2000.
For details about any of the suppressors or for information about selecting
a suppressor for your application, refer to the suppressor manuals. The
manuals are on the Dionex Reference Library CD-ROM (P/N 053891).
The column heater provides temperature
control for the separator and guard column.
The heater temperature can be set to between
30 and 60 °C. However, the set temperature
must be at least 5 °C above the ambient
temperature. A thermistor mounted in the
heater block monitors the temperature.
Setting the temperature to 0 °C turns off the
column heater.
If the temperature exceeds 65 °C, the
column heater is shut off and the error
message “Column heater exceeds safe
temperature.” is displayed on the touch
screen and in the Chromeleon Audit Trail.
See
Section 4.1 for troubleshooting
information.
