42 Agilent Intuvo 9000 GC Installation
1 Installing the GC
Prepare gas supplies.
Most of installation involves plumbing gas to tanks, filters, and
flow modules. Swagelok fittings are used to make leak-tight
connections. If you are not sure how to make a Swagelok
connection, see Appendix A for instructions.
Install the gas regulators
1 Select the appropriate CGA regulator for each gas type. (In
other countries, refer to local standards. See the Agilent
Intuvo 9000 GC, GC/MS, and ALS Site Preparation Guide for
requirements.)
2 Confirm that the outlet fitting of the regulator is 1/8-inch
Swagelok. If not, install the appropriate adapter fitting. Wrap
the fitting threads using PTFE tape. Wrap the tape in a
clockwise direction so that the adapter threads do not
unwrap the tape. Be careful to keep the tape away from the
end of the fitting. Two to three tightly wound wraps are
sufficient. Never use a liquid thread sealant. Liquid thread
sealants introduce contamination into the GC plumbing
system. Tighten the Swagelok adapter fitting securely to the
NPT pipe thread fitting.
Hydrogen is a flammable gas. If hydrogen or any other flammable
gas is used, periodic leak tests should be performed. Be sure that
the hydrogen supply is off until all connections are made.
Substituting parts or performing any unauthorized modification to
the instrument may result in a safety hazard.
