Manually Heating the Graphite Tube
To enter the temperature manually and heat the furnace:
1. On the
Toolbar
, click on

.
2. In the
Furnace Control
window, click on the
Cleanout Temp.
entry field and
type the required temperature (e.g. 2500 °C).
Warning: High Temperatures – Risk of Burns
The graphite furnace can generate very high temperatures. Do
not
touch
any parts of the furnace, especially the graphite components, until they
have cooled to room temperature.
Warning: UV Radiation – Risk of Eye Damage
When the graphite furnace is heated to incandescence (approximate
temperature, such as higher than 800 °C.), e.g. during the pyrolysis and
atomization steps, the furnace can emit UV radiation which can damage
your eyes.
Always wear UV-absorbing safety glasses when looking at the
furnace.
Warning: Toxic Gases
If you use nitrogen as the inert gas, toxic cyanogen gas (CN)
2
will be
produced when the furnace temperature is above 2300 °C.
Make sure that the main laboratory fume ventilation system removes
all gases and fumes emitted by the furnace.
Note
Do
not
heat the graphite furnace for longer than about 10 s when the
temperature exceeds 2000 °C. Heating for longer periods will markedly
reduce the lifetime of the graphite tube.
