Running a TGA Experiment
Stopping
an Experiment
If for some reason you need to discontinue the
experiment, you can stop it at any point by
pressing either the STOP key on the TGA 2950
keypad or Stop on the on the TGA Instrument
Control program (see the online help and docu-
mentation for further information). Another
function that stops the experiment is Reject.
However, the Reject function discards all of the
data from the experiment; the Stop function
saves any data collected up to the point at which
the experiment was stopped.
The Heat Exchanger will continue to run as long as
the Air Cool option is activated or until the indi-
cated temperature is below 50
o
C.
The REJECT function discards all experiment data.
Unloading
the Sample
If you select the method-end option that enables
the furnace to open and unload at the end of the
experiment, the TGA will automatically unload
the sample at the end of the run. (See the online
help and documentation for further information.)
If you need to unload the sample manually, wait
until the run and all method-end operations are
complete, and then press the UNLOAD key.
The sample pan may not line up with the sample
platform groove at method end.
