Introducing the Discovery TGA
Overview
Your TA Instruments Discovery Thermogravimetric Analyzer (Discovery TGA) is used in conjunction
with a controller computer and associated software to make up a thermal analysis system.
The Discovery TGA measures the amount and rate of weight change in a material, either as a function of
increasing temperature or isothermally as a function of time, in a controlled atmosphere. The TGA can be
used to characterize any material that exhibits a weight change and to detect phase changes due to decom-
position, oxidation, or dehydration. This information helps the scientist or engineer identify the percent
weight change and correlate chemical structure, processing, and end-use performance.
Your controller is a computer that performs the following functions:
•
Provides an interface between you and the analysis instrument
•
Enables you to set up experiments and enter parameters
•
Stores experimental data
•
Runs data analysis programs.
