MultipleGas #3GC configuration
Another example uses a 9’ HaysepD
column and a 6’ MoleSieve 13X. With
the event table set to the “ TimingMode”
we can see there is a nice gap at 1.5
minuteswherewe can actuate theStop-
Flow solenoid. TheStop-Flow chroma-
togram separates theO2, N2 andCO on
the 13X column, then theMethane and
CO2 on theHaysep column .

Solenoid on at 1.5
minutes
Solenoid
Off at 4.00
TheStop-Flow solenoid is actuated at 1.5minutes and
de-energized at 4.00minutes. The valve is rotated
back to Load also at 4.00minutes

The gap in the chromatogram between the combined
O2, N2 andCO peak and theMethane peak is a good
place to actuate theStop-Flow solenoid
