Features:
Fully Automated
² The flame and graphite furnace is integrated into one instrument.The change over from one technique to another is
carried out by simple key strokes within the software.
² The instruments have a motorised 8 hollow cathode lamp turret which allows the automatic positioning and
optimisation of each hollow cathode lamp by the software.
² The control of the gas flows for the fuel gas (C2H2 ) and the positioning of the bumer is also carried out directly from
the software thus allowing optimization of the instruments for the best analytical parameter for a selected analysis.
² Two methods of background correction are available.The first utilises a deuterium lamp and the second is the proven
method of self reversal.
² The location of the wavelength and peak selection is automatic and controlled from the software. The spectral
bandwidth is automated and is available with a choice of five slit sizes.
² The electronic parameters for the photomultiplier detector,the hollow cathode lamp current and the balancing of the
absorbance and background energies are controlled from the software.
² The igntion of the flame is computer controlled and the various safety interlocks offer a very safe operating system.
