The methods of thermal analysis are descriptive analytical techniques. With their help, the temperature-dependent changes in material properties can be described. To characterize them, the methods like dilatometry (DIL), thermogravimetry (TGA) and differential scanning calorimetry (DSC) are applied.
Samples can be investigated in even more detail by combining these descriptive thermoanalytical methods with identifying techniques. In fact, heating a sample induces the release of volatile compounds initially present in the material or generated during the heating cycle. Combining thermal analytic techniques like TGA with spectroscopic techniques like FT-IR and GC-MS provides a powerful tool to identify these compounds evolving during a specific weight-loss event in a TGA analysis.
This webinar will give a brief introduction to the basics of gas analysis like FT-IR and GC-MS, discusses the advantages of combining spectroscopic techniques with TGA and presents advice on how to recognize critical volatile content in polymers.
