Flame Atomiser Features
The flame atomiser offers three flame options:
Air/acetylene is the standard configuration with the N2O/acetylene and Air/LPG as options.

Air/Acetylene 
The Air/Acetylene flame uses a 100mm single slot burner for the standard configuration.
The high sensitivity (Cu 2ppm >0.280abs) is due to the efficiency of the fixed position glass nebuliser fitted as standard. An acid resistant replacement is available as an option.
The flame can be easily set from blue lean flame through stoichiometric to fuel rich by means of computer control.

N20/Acetylene
The N2O/Acetylene flame uses a 50mm single slot burner and is available as an optional extra. (This burner is also known as the UNIVERSAL Burner.
This flame configuration is used to measure elements less prone to ionization such as: Aluminium, Tin, Titanium, Calcium, Vanadium and Molybdenum.Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWinPro software.
