Another example isNatural Gas. Set
theEvent table up to inject and then im-
mediately rotate the valve back to Load
after .1minutes in the Inject position.
This has the effect of performing the
analysis as if Column2was not in the
system. We call this the “ TimingMode”
Column 1 is a 3’ HaysepD andColumn
2 is a 6’ MS13X. TheHaysepD does
not separateOxygen andNitrogen or
CO. Set theStop-Flow solenoid time by
finding the gap betweenMethane and
CO2, in this case about .9minutes.
