Features and Functions
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 com-puter 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: Aluminium, Tin, Titanium, Calcium, Vanadium and Molybdenum.
Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWin3.0 software.
Air/Propane(LPG)
This flame uses a 3 slot burner and with the Iow pres-sure requirement it is also much safer to operate.
Due to the Iow temperature of the flame it is ideal for analysing alkali metals such as: Potassium, Sodium and Lithium, especially when used in the emission mode.
Some remote areas of the world have difficulty obtain-ing 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.

AA-Win Pro Software is a powerful and intuitive software product designed to allow control and data acquisition from the AAS-3800 Atomic Absorption Spectrometer.
The AA-Win Pro software allows the Analyst to control all aspects of their analytical method while providing an extensive range of tools for data collection, storage and interpretation.
The software interface consists of three key workareas, whilst having toolbars to access many others. These work areas allow the user to view real-time signal acquisition, up-to-date display of calibration curves and a flexible sample table.
Lamp turret setup, operating and warm-up currents, along with the desired analytical wavelength are easily selected in the configuration.
