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.
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.
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.
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.
