Graphite Furnace
- Integratedcomputer-controlledTransverselyHeatedGraphiteFurnace
- Graphite tube is transversely heated to provide a constant temperature profile over the entire length of the tube and to reduce matrix interferences
- Independent gas controls for the external and internal gas flows around and through the tube allow easy removal of volatile matrices whilst protecting the tube from outside air during the internal gas stop hence maximizing tube life
- The advanced furnace concept, utilising the adaptive sensor-less temperature control and emission independent temperature control ensures constant, precise, reproducible and accurate temperature conditions from analysis to analysis, batch to batch
- Changeoverfromflametofurnaceorbackisextremelyeasyandpneumaticopeningand closing of the furnace allows easy change of tubes or electrodes
- Optionalhigh-endvisiontool-furnacecamera Functions Analytical programs with up to 20 steps can be set up and all steps are easily programmable, safety interlocks monitor all important parameters
