Cleaning the
Furnace Housing
Do not touch the EGA furnace sample tube
with your bare fingers. Skin oils may cause
devitrification of the quartz glass, resulting
in severely reduced sample tube life. Do
not insert instruments inside the sample
tube to scrape or chip contaminants from
the sample tube as breakage may result.
TGA Standard
Furnace Only
To ensure long furnace life, we recommend that
you clean the furnace housing at least once a
month to remove condensation materials. Follow
steps 1-6 to remove furnace housing (page 5-8
and 5-9). Disconnect the purge line and invert
the furnace housing over paper towels. Clean the
inside with a solvent and cotton squabs. Be sure
to dry the housing and purge ports with air to
remove any solvent traces before replacing the
furnace housing. Follow the instructions on page
5-10 and 5-11 for replacing the standard furnace
housing. After replacing the furnace, heat the
TGA to 900
°
C to remove any remaining solvent.
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 standard furnace more frequently
to prevent dangerous buildup of debris in the
furnace. This is particularly important if you
are using oxygen as a purge gas.
