TA I TGA 2050
NSTRUMENTS
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. This is particularly important if
oxygen is used as a purge gas in the TGA
2050. See Chapter 5 for instructions.
The TGA 2050 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.
During a sample run, the furnace base can
be hot enough to burn skin. Avoid contact
with the furnace base during experiments.
Keep your fingers and all other objects out
of the path of the furnace when it is mov-
ing. The furnace seal is very tight.
