Webinar – Fundamentals of TGA Analysis

The TGA Technique Characterizes Materials by Measuring Changes in Mass as a Function of Temperature

Thermogravimetric analysis (TGA) is widely used together with DSC, TMA, and DMA. TGA measures the mass of a sample while the sample is heated or cooled in a defined atmosphere. The main use of TGA is to characterize materials with regard to their composition. A TGA/DSC instrument even allows you measure thermal events that do not produce a mass change such as melting, glass transitions, or other solid-solid transitions.

In this webinar, we will discuss the basic principles of TGA/DSC and present some interesting applications.

The TGA technique measures the mass of a sample as it is heated, cooled or held at a constant temperature in a defined atmosphere. Thermogravimetric analysis (TGA) is ideal for characterizing the thermal properties of materials such as plastics, elastomers and thermosets, mineral compounds and ceramics as well as for chemical and pharmaceutical products.

TGA/DSC and hyphenated techniques
TGA is often used together with Differential Scanning Calorimetry (DSC) because the two techniques provide complementary information, which often facilitates the interpretation of a thermal analysis experiment.

The gaseous products that are evolved can be analyzed using hyphenated techniques, for example by coupling a Fourier transform infrared spectrometer (FTIR) or a mass spectrometer (MS) to the thermobalance of the TGA instrument.

TGA applications
The properties and behavior that can be measured by the TGA technique include composition, purity, decomposition reactions, decomposition temperatures, and absorbed moisture content.

This webinar presents several different application examples that demonstrate the analytical power and versatility of TGA/DSC.
