Table 5-1. Required Pressures for the Burner Gases
• Set the outlet gauge pressure for each gas to a value just below the
maximum value (see Pmax column).
• Always set the same outlet gauge pressure for air and nitrous oxide.
• Never set the outlet gauge pressure to a value exceeding the maximum
pressure (see Pmax column).
• Always turn on the air supply since air pressure is required for the
spectrometer's pneumatic system.
Warning: Acetylene - Explosion Hazard
Acetylene can decompose explosively at pressures higher than 103 kPa/
1.03 bar/15 psig.
Always make sure that the acetylene outlet gauge pressure is below this
value.
Warning: Flashback Hazard
Never set up the nebulizer using a nitrous oxide-acetylene flame.
• Set up the nebulizer using an air-acetylene flame only, and make small
adjustments slowly.
