The integrated graphite furnace atomiser is available in
2 formats:
– In the AA500G instrument the graphite furnace head is
fixed into the light path.
– In the AA500FG instrument the graphite furnace head is
fixed behind the flame atomiser assembly and is
motorised into position by a simple operation in the
AA-Win software.
Furnace Head Design
– The Transverse head is heated and cooled efficiently
due to the feedback system and has been designed to
reduce analytical problems normally associated with this
type of technique.
– Pyrolytically coated graphite tubes are used as standard
and are manufactured to improve performance as well
as increase the analytical life.
– Platform Tubes are supplied as standard and will accept
volumes up to 20ul.
Heating Program
– Up to 10 heat stages are available. These can be set up
and stored in the AA-Win software.
The graphite furnace tube is cooled efficiently by an
optional water circulation system.
