Inlets 3
Advanced User Guide 37
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. For EPR equipped GCs, you can
manually adjust this parameter using the 2/+ and 8/- keys on
the software keypad.
Total flow 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.
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.
NOTE
There is no setpoint for the Pressure parameter in EPR (electronic
pneumatics regulation) equipped GCs with an S/SL inlet.
NOTE
There is no setpoint for the Total flow parameter in EPR (electronic
pneumatics regulation) equipped GCs with an S/SL inlet.
NOTE
There is no setpoint for the Purge flow parameter in EPR (electronic
pneumatics regulation) equipped GCs with an S/SL inlet.
NOTE
Gas saver is not supported on EPR (electronic pneumatics regulation)
equipped GCs.
