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.
