MultipleGas #3GC configuration
Instead, theMG#3
allows theStop
Flow solenoid to
actuate at 3.5min-
utes just after the
Propane andCOS
migrate intoCol-
umn 2 ( 15meter RTXQPlot .53mm ).
This traps the peaks after Propane in
Column 1while the peaks inColumn 2
(Methane, Ethane, Propane, H2S and
COS ) separate and elute. Unlike col-
umn 1which does not separateCOS
andPropane, the peaks arewell sepa-
rated onColumn 2 so quenching does
not occur.
OncePropane elutes fromColumn 2
( about 10minutes ) the valve rotates
back to the Load position and theStop
Flow solenoid is de-energized. The
peakswhichwere trapped on column 1
now elute to the detectors ( Butanes,
Pentanes, Mercaptans etc. )
