Connecting
the Spectrometer
The TGA 2950 EGA furnace allows you to
connect a spectrometer, such as a FTIR spec-
trometer, to the instrument. To connect any
spectrometer, you will need to use a transfer line
(supplied by the spectrometer manufacturer) to
transport the gas evolved from the sample on the
TGA to the spectrometer.
•
The transfer line should be 1/8 inch in
diameter to connect with a 1/8-inch
Swagelok
TM
fitting on the exhaust gas
connection.
•
The transfer line should be made of heat-
resistant alloy capable of resisting
corrosion by the evolved gas and oxidation
at temperatures up to 1000°C.
•
The transfer line must pass through the
exhaust gas fitting and a glass branch tube
in the sample tube. It should end at a point
just short of the inside diameter of the
sample tube to ensure that the evolved gases
do not condense before entering the transfer
line.
•
The transfer line must be long enough to
allow flexible movement. It must
accommodate movement of the EGA
furnace up and down 3 5/8 inches to open
and close for sample loading and unloading.
(If the transfer line is not long enough, it
must be disconnected and reconnected each
time the furnace is opened and closed.)
