58 Agilent Intuvo 9000 GC Installation
1 Installing the GC
Connect valve actuator air (if present).
Valves are driven by air actuators. Valves should have a
dedicated air source; they cannot share detector air supplies.
Valves can use nitrogen as an alternate supply. In this case, the
nitrogen does not have to be chromatographic grade but must be
free from contaminants.
Valve actuator air is supplied through 1/4-inch plastic tubing. If
your GC was ordered with valves, the plastic tubing will already
be attached to the actuators and will extend from the back of
the GC.
Turn off the air supply at the source. If needed, shorten the
supplied plastic tubing using a sharp knife. Connect the tubing
to the air source using a 1/4-inch Swagelok nut and ferrules.
Do not share air between a detector and valves.
Route the tubing away from the GC hot air exhausts. The hot air will
melt the plastic tubing.
