8 Inlets
Setting parameters for the S/SL splitless mode
Mode The current operating mode—splitless
Oven temperature Below solvent boiling point
Tem pe ratur e 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.
4 Enter a Purge time and a Purge flow.
5 If desired, turn on Gas saver. Make certain the time is set
after the Purge time.
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
