the minimum oven temperature is 40°C or 15°C above ambient, whichever is
greater.
Use the down cursor key (
Key in the desired sample–loop temperature (within the allowed range of
0–220°C for the G1289/G1290, 50–220°C for the G1883) followed by Enter. Use
the down cursor key (
Key in the desired setpoint on the numeric keypad for the transfer line
temperature followed by Enter. The allowed range is 0–220°C for the G1289/
G1290 or 50–220°C for the G1883.
Note
As a general rule, the loop and transfer line temperatures should be set higher
than the oven temperature. Set the loop temperature 15°C higher than the
oven, and set the transfer line 25°C higher than the oven.

Setting Event Times

Using this key, you enter values in minutes for the timed events which make up
the vial sampling sequence. Pressing Event Times displays the first timed
event:
From the numeric keypad, enter a value for this event, which is the time for the
total GC run to complete. (Total run includes the GC run and cool–down time
and the vial equilibration time.) Press Enter after keying in the numeric value.
Use the down cursor key (
The Vial Equilibration Time is the time which the sample vial spends heating in
