If you do not have a bypass option or want to shut off the gas completely anyway
proceed as follows: While the gas is still flowing, first remove the column from the ECD
detector and close the opening with a blind plug (ferrule with wire inside). Then cap
the ECD vent in the back of the GC with a G-type plug and three aluminium gaskets
that come with your Shimadzu GC. Make sure both openings are sealed properly and
no gas can pass through. This will fill the ECD cells with the inert Makeup Gas.

tep 4: Turn off GC power
When the GC is completely cooled, the GC power may be turned off. The electronic gas
flow controllers will stop when the GC is powered off. Manual flow controllers must be
turned off by the users (use cut-off valves or turn the regulators off). We recommend
for long-term shutoff, turn the gas tanks off as well.
