Caution
Oven temperature should not exceed 10°C below the boiling point of any
solvents in the vial. Exceeding this may cause the cap and septum to leak or to
pop off; the vial pressure line could also become contaminated.

Event Times

Pressing Event Times brings up the first menu item:
The cursor keys allow scrolling through the list of events. They are the
following:
Event
GC CYCLE TIME
VIAL EQ. TIME
PRESSURIZ TIME
LOOP FILL TIME
LOOP EQ TIME
INJECT TIME
GC CYCLE TIME
The time required for the entire GC run to be completed. It is the sum of the GC
run time and GC equilibration time (read from the GC front panel) and an
estimate of the cool–down time required (if any). This time allows the 7694
Headspace Sampler microprocessor to introduce samples into the oven most
efficiently and avoid injecting a sample before the GC is ready. The allowed
32
temperature 15°C higher than the oven, and set the transfer line 25°C
higher than the oven.
To set the oven temperature at 40°C, set the loop temperature at 40°C. The
minimum oven temperature is approximately 15°C above ambient.
