Running a Discovery TGA Experiment
All of your TGA experiments will have the following general outline. In some cases, not all of these steps
will be performed. See TRIOS software Online Help for anything not covered in this manual.
1
Attaching and setting up external accessories and/or environmental conditions as required, such as the
purge gas
2
Selecting the pan size and material
3
Taring the empty sample pan
4
Loading the sample into the pan
5
Entering experiment information in TRIOS software; this includes both sample and instrument
information.
6
Creating or selecting the experimental procedure using TRIOS software
7
Starting the experiment
Selecting the Pan Size and Material
Choose a pan based on the desired temperature range and application. See
System" on page 25
for the pans that can be used with the Discovery TGA Autosampler.
Taring the Sample Pan(s)
Taring of all sample pans on the tray must be done before the sample is loaded to ensure that the balance
gives you an accurate reading.
NOTE: A sample pan of the same size and type that will be used for your experiments is required on the
tare side for proper operation.
1
Place clean, empty pan(s) on the platform. If you are using sealed aluminum pans, then you must tare
the lid along with the empty pan. See TRIOS software Online Help for more information.
2
Specify the pan type in TRIOS software. Only pans of the same type may be run in the same sequence.
3
Select the Tare button on the user interface. Alternatively, select Tare from the Instrument tab within
TRIOS software.
4
Select the desired pans, then select Start from the user interface or from TRIOS to initiate the tare
procedure. The pan will automatically be loaded and the furnace raised to make the measurement. When
the tare procedure is complete, the furnace automatically lowers and unloads the pan.
