The TGA 2950 furnace assembly contains a
layer of refractory ceramic fiber (RCF)
insulation. This insulation is completely
encapsulated within the ceramic subassem-
bly, which is not meant to be disassembled.
If the subassembly should break in such a
way as to expose the RCF insulation, we
recommend that you dispose of it as you
would any refractory material.
If you are routinely evaluating materials in
the TGA that lose a large amount of volatile
hydrocarbons ( e.g. , lubricating oils), you
need to clean the furnace more frequently
to prevent dangerous buildup of debris in
the furnace.
If you are using samples that may emit
harmful gases, vent the gases by placing
the instrument near an exhaust.
The TGA 2950 EGA furnace assembly also
contains refractory ceramic fiber (RCF)
insulation. This insulation is enclosed
within the furnace housing. The furnace
housing should only be disassembled for
replacement of EGA furnace sample tube or
furnace assemblies. Refer to instructions
provided with the sample tube or furnace
replacement kits for procedures for han-
dling RCF insulation.
