4 Columns and Oven
• Position 2 Carrier gas flows through the column toward the
inlet, removing components on the column through the inlet
vent line.
The Run Table contains commands to perform these actions:
• After the last peak of interest appears, switch the valve to
Position 2. Higher boiling peaks are discarded through the
inlet vent.
• At the same time, turn data acquisition off.
• At the end of the backflush period (determined
experimentally), switch the valve to Position 1 and turn data
acquisition on. The system is now ready for the next run.
