Product Detail
Flame AA System AA500F 0.1, 0.2, 0.4, 1.0, 2.0nm Atomic Absorption Spectrophotometer
Flame AA System AA500F 0.1, 0.2, 0.4, 1.0, 2.0nm Atomic Absorption Spectrophotometer
The flame atomizer 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 nebulizer 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
N2O/Acetylene
The N2O/Acetylene flame uses a 50mm single slot burner and is available as an optional extra.
This flame configuration is used to measure elements less prone to ionization such as Aluminum, Tin, Titanium, Calcium, Vanadium and Molybdenum.
Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWin Pro software
Air/Propane (LPG)
This flame uses a 3 slot burner and with the low pressure requirement it is also much safer to operate
Due to the low temperature of the flame it is ideal for analyzing alkali metals such as Potassium, Sodium and Lithium, especially when used in the emission mode.
Some remote areas of the world have difficulty obtaining Acetylene gas of a high enough purity to operate the flame correctly. LPG can give a real alternative and offer comparable results for most elements throughout the wavelength range.
