Introduction to TGA, STA and Evolved Gas Analysis in Pharmaceutical Characterization

Understanding composition, thermal stability and decomposition behavior is essential throughout pharmaceutical development and quality control. Thermogravimetric Analysis (TGA) detects changes in sample mass, revealing valuable information about moisture, volatile components, degradation processes and material composition.

In Part 3 of our Pharmaceutical Characterization Webinar Series, we introduce the fundamentals of TGA, Simultaneous Thermal Analysis (STA) and Evolved Gas Analysis (EGA). Learn how the instruments work, how to develop reliable measurement methods and how to interpret mass-loss and gas-analysis signals.

Application examples will demonstrate how TGA and EGA support the characterization of APIs, excipients and pharmaceutical formulations. The session also prepares participants for the following webinar, which will explore practical applications and real-world case studies in greater detail.
