MultipleGas #3GC configuration
ApplicationExample-2 step process
The results of the
Step1 chroma-
togram is shown at
right. Since the
peaks only traveled
through theHaysep-
D column there is no
separation of Hydro-
gen, Oxygen, Nitro-
gen or CO. Those
peaks all elute to-
gether in one big
peak. It is clear
from the chroma-
togram that an ap-
propriate time to ac-
tuate theStop-Flow
solenoidwould be at
about 2.3minutes. This is just after the
methane peak and before theCO2
peak.
The event table ismodified so that Relay
Awhich controls theStop-FlowSolenoid
is turned on at 2.3minutes.
Notice that the entry for RelayG off is
removed ( compared to the first Event
table ) sincewe do not know at this time
when to do this. This iswhat will be de-
terminedwhenwe re-inject the same
sample inStep 2.
