About Gas Saver
Gas saver reduces carrier flow from the split vent after the
sample is on the column. It applies to the Split/Splitless inlet
(all modes). It is most useful in split applications.
Column head pressure and flow rate are maintained, while
purge and split vent flows decrease. Flows—except column
flow—remain at the reduced level until you press [Prep Run].
NOTE
Gas saver is not supported on EPR (electronic pneumatics regulation)
equipped GCs.
