A 10 port Valco gas sampling valve is
mounted in the heated valve oven.
The valve is plumbed as shown in the
diagram.
In the Load position the
carrier gas flows
through the three col-
umns and into the de-
tectors but the sample
loop is isolated so sam-
ple can be loaded into
the loop.
When the analysis is
started, the valve ro-
tates to the Inject posi-
tion so the carrier gas
now pushes the sample
out of the loop, to the
“tee” fittingwhere it
splits into two paths.
