The Burner System

The burner system used in the spectrometer system is of the premix design. The measurement
solution is sprayed by a pneumatic nebulizer into the burner chamber in the form of an aerosol.
This aerosol is thoroughly premixed with the burner fuel and oxidant gases in the burner
chamber. This gas mixture then passes through the burner slot into the flame.
The burner system comprises the following major components:
• Nebulizer
• Burner chamber (including the flow spoiler and end cap)
• Burner head
• Drain system
• Gas control system (incorporated in the spectrometer)
