Setting up the System for Analyses Using the Flame Technique
Select an air-acetylene flame:
• – If you are setting up the burner system.
• – If you have installed a different nebulizer, cleaned the nebulizer, or if the
settings on the nebulizer have been altered since it was last used.
• – If you are using the flame to heat the quartz-cell.
For the correct procedure to extinguish the flame see Extinguishing the Flame on
page 179 .
Extinguishing the Flame
Before you extinguish the flame or begin maintenance or disassembly procedures,
you must rinse the burner system. After you extinguish the flame, allow the burner
head to cool.
Warning: UV Radiation – Risk of Eye Damage
The flame, especially the nitrous oxide-acetylene flame, may emit UV
radiation which can damage your eyes.
• Keep the door closed when the flame is burning, unless you need to
adjust the burner as described in the user documentation.
• Always wear UV-absorbing safety glasses when looking at the flame.
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.
