Most of installation involves plumbing gas to tanks, traps, and
manifolds. Swagelok fittings are used to make leak-tight
connections. If you are not sure how to make a Swagelok
connection, see Appendix
instructions.
Front and back views of the 6820 GC are shown in
Figure 3.
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, and insure that
the inlet fittings are either connected to a column or capped at all
times when hydrogen gas is present in the instrument.
Substituting parts or performing any unauthorized modification to
the instrument may result in a safety hazard.
The insulation around the inlets, detectors, valve box, and the
insulation cups is made of refractory ceramic fibers (RCF). To avoid
inhaling RCF particles, we recommend these safety procedures:
ventilate your work area; wear long sleeves, gloves, safety glasses,
and a disposable dust/mist respirator; dispose of insulation in a
sealed plastic bag; wash your hands with mild soap and cold water
after handling RCFs.
