Thermogravimetric analysis (TGA) is used to characterize physical and chemical material properties as a function of temperature in a precisely controlled atmosphere. The method provides valuable information for quality control, development, and research. Application areas include thermoplastics, elastomers, thermosets, metals and ceramics as well as a wide range of analyses in the chemical, building, food and pharmaceutical industries. 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.
A TGA/DSC instrument is even more versatile because it combines a TGA with a DSC. The system can be coupled on-line to a mass spectrometer or FTIR spectrometer to identify the nature of evolved gaseous products. Combined with a humidity generator it can also be used to study sorption processes.
The presentation covers the following topics:
- Principles of TGA
- TGA/DSC 1
- Measurement possibilities
- Why use TGA?
- Industries and applications
In this presentation, we will discuss the basic principles of TGA/DSC and present some interesting applications.
