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.
