Connecting the Gases
What is Provided With the Spectrometer
• Gas hose assemblies for acetylene, air, and nitrous oxide. The fittings on the
gas hose assemblies are suitable for connection to most commercially available
pressure regulators. These are R 3/8'' standard threaded fittings. The fuel
(acetylene) fitting has a left-hand thread, while the oxidant (air, nitrous oxide)
fittings have right-hand threads.
If you require an adapter for your regulator, contact the gas supplier or the
regulator manufacturer, or your local PerkinElmer office.
• The instrument ships with standard US gas line configurations. For European
gas connection adapters see the figure on page 111.
Connecting the Gases
Refer to the figure on page 110, Connecting the burning gases.
Air
1. Make sure that the air supply is turned off.
2. Use the black hose assembly to connect a source of clean, dry, and filtered air
to the fitting labeled Air on the rear panel of the spectrometer. Use an
adjustable wrench to tighten the connections.
Nitrous oxide
1. Make sure that the nitrous oxide supply is turned off.
2. Use the blue N
2
O hose assembly to connect a source of clean, dry nitrous oxide
to the fitting labeled N
2
O on the rear panel of the spectrometer. Use an
adjustable wrench to tighten the connections.
Warning: Flashback Hazard
PerkinElmer burner systems are designed for use with compressed air.
The use of oxygen can cause an explosion in the burner system, and
oxygen-enriched air can cause a flashback of the flame.
Never use oxygen or oxygen-enriched air with PerkinElmer burner
systems. Use only compressed air.
