Inlets 3
Advanced Operation Manual 53
Setting parameters for the S/SL splitless mode
Mode The current operating mode—splitless
Oven temperature Below solvent boiling point
Tempera ture Actual and setpoint inlet temperatures
Pressure Actual and setpoint inlet pressure in psi, bar, or
kPa
Purge time The time, after the beginning of the run, when
you want the purge valve to open. This is the time in which
the vaporized sample transfers from the liner to the column.
Purge flow The flow, in mL/min, from the purge vent, at
Purge time. You will not be able to specify this value if any
column in the flow path is not defined.
Total f l ow The actual flow to the inlet during a Pre- run
(Pre- run light is on and not blinking) and during a run
before purge time. You cannot enter a setpoint at these
times. At all other times, Total flow will have both setpoint
and actual values.
Septum Purge Flow, in mL/min, through the septum purge
line.
Septum Purge Flow Mode Standard (septum purge flow is On
at all times) or Switched (septum purge flow is Off during
injection, turns On at Purge time).
If all columns in the flow path are defined
1 Press [Front Inlet] or [Back Inlet].
2 Scroll to Mode: and press [Mode/Type]. Select Splitless.
3 Set the inlet temperature.
Gas saver time 0 to 999.9 minutes After purge time
Gas saver flow 15 to 1000 mL/min 15 mL/min greater than
maximum column flow
