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.
