Column Temperature
In isothermal operation the columns are maintained at a fixed temperature. Retention
time drift is virtually eliminated and faster analysis results are obtained with less
frequent calibration. The PID is maintained at the same temperature as the columns.
NOTE: Do not set the temperature to below 40 C, as samples may condense on the column
and contaminate your system.
1. Press Enter Menu, SETUP, CONFIG, COLUMN.
2. Select the column for which you want to alter the column temperature. Disable
the other columns.
3. Press Exit to close the box. Press Enter Menu to close the menu.
4. Press Enter Menu, SETUP, CONFIG, METHOD, TEMP, and COLUMN.
5. Use the arrow keys to enter the new column temperature. Press Enter Menu.
Explorer will allow you to set the temperature to between 0 and 80 °C. It is not
advisable to set the column temperature to less than 40
°C.
6. If you need to change the column temperature for the other two columns,
repeat this procedure for each column.
7. When you have changed the column temperature for each column, enable all
the columns required for your method.
If you have entered different temperatures for each column, Explorer will require 20
to 30 minutes between analyses to reach the column temperature.
