within the sample tube do not come in contact
with the resistance elements or the furnace
ceramic refractory.
Cooling air enters through the furnace base and
passes upward between the outside of the
sample tube and the inside of the furnace,
completely separating the cooling air from the
sample and the sample zone.
The furnace is a resistance heater wound on
alumina ceramic, which allows sample zone
temperatures as high as 1000°C with heating
rates up to 50°C/min.
The thermocouple and furnace base are the
same as those described above for the standard
TGA furnace.
