46 Advanced Operation Manual
3 Inlets
Split/Splitless inlet splitless mode overview
In this mode, the split vent valve is closed during the
injection and remains so while the sample is vaporized in
the liner and transferred to the column. At a specified time
after injection, the valve opens to sweep any vapors
remaining in the liner out the split vent. This avoids solvent
tailing due to the large inlet volume and small column flow
rate. Specify the purge time and purge flow rate in the inlet
parameter list.
The septum purge flow may be either on at all times
(Standard mode) or on only between the purge time and the
end of the run (Switched mode).
If you are using gas saver, the gas saver time should be after
the purge time.
