Using the Discovery TGA
All of your TGA experiments will have the following general outline. In some cases, not all of these steps
will be performed. The majority of these steps are performed using the instrument control software. The
instructions needed to perform these actions can be found in the online help in the instrument control
program; therefore, they will not all be covered in detail here.
• Calibrating the instrument
• Selecting the pan size and material
• Selecting the purge gas and setting flow rates
• Creating or choosing the test procedure and entering experiment information in TRIOS software
• Selecting and taring the sample pan
• Loading the sample
• Starting the experiment
• Unloading the sample at the end of the experiment
To obtain accurate results, follow procedures carefully and check calibration periodically (once a month).
Before You Begin
Before you set up an experiment, ensure that the Discovery TGA system and the controller have been
installed properly. Make sure you have:
• Connected the instrument with the controller
• Connected all gas lines
• Connected heat exchanger power and water lines
• Installed any desired options
• Powered up the Discovery TGA and heat exchanger
• Become familiar with controller operations
• Calibrated the Discovery TGA, if necessary
