Conditioning the Column and Inlet System
Conditioning the Column and Inlet System
As the column and inlet system have not been thermally cycled as a unit, it is
necessary to accomplish this conditioning more slowly. While thermally cycling
the GC, start the MSD preparation.
1 Once all initial temperatures have equilibrated, start PREP_RUN by
selecting the START (F8) key from the Status screen in the Control
Module or by selecting Start on the GC keypad.
While the oven is heating proceed with the MSD preparation.
2 Once the oven temperature exceeds 80° C, inject 5 uL of methanol. Repeat
2 more times at 15 minute intervals.
3 When the oven temperature has cooled to 35° C (see the Status/Settings/
Oven screen), set the injection port to OFF.
4 When the injection port has cooled below 100° C (see the Status/Settings/
Inlet screen), turn the GC power off.
