2 Operating Basics
To Shut Down the GC for More Than a Week
See Maintaining Your GC manual for procedures for
installing columns, consumables, and so on.
1 Load a GC maintenance method and wait for the GC to
become ready. For more information about creating
maintenance methods, see the Maintaining Your GC
manual. (If a maintenance method is not available, set all
heated zones to 40 °C.)
2 Turn off the main power switch.
3 Shut off all gas valves at the gas source.
4 If you are using cryogenic cooling, shut off the cryo
coolant valve at the source.
5 When the GC is cool, remove the column from the oven
and cap both ends to keep out contaminants.
6 Cap the inlet and detector column fittings and all GC
external fittings.
Be careful! The oven, inlet, and/or detector may be hot enough to
cause burns. If they are hot, wear heat-resistant gloves to protect
your hands.
