Connecting the burner gases
The connectors for the burner gases are located on the rear panel of the
spectrometer.
What you need to provide:
Suitable supplies of acetylene, air, and nitrous oxide. The gases must conform
with the requirements listed in Chapter 6, Laboratory Requirements.
Suitable pressure regulators and on/off valves near to the spectrometer for the
gas supplies.
The gas supply systems must comply with your local safety regulations.
Refer also to the information given in Chapter 1, Safety and Regulatory
Information.
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.
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.
