Comments
If in Custom mode, set the final sample loop
pressure. If in Default mode, the final pressure
is displayed. See "Filling the sample loop"
more information.
If in Custom mode, default value: 0.05 minutes.
Default: Yes. During an injection cycle that
starts a GC run, vent residual vial pressure.
Press [Mode/Type] to select.
Shaking is available in 9 levels. See
shaking. Enter the value (1 through 9) directly, or
enter 0 to disable.
Comments
For reference, the HS internal pressure reading
for the carrier gas.
Comments
The current pressure reading. If in pressure
mode, also includes the column pressure
setpoint.
The current flow rate. If in flow mode, also
includes the column flow setpoint.
Press [Mode/Type] to select the carrier gas
control mode:
•
Pressure mode: Control the carrier gas
pressure, whether ramped or constant.
•
Flow mode: Control the carrier gas flow,
whether ramped or constant.
