A Tutorial on Thermogravimetric Analysis (TGA)

Thermogravimetric analysis (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.

Overview

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.

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.

In this webinar, we will discuss the basic principles of TGA and present some interesting application examples. Attendees will learn the advantages of using different temperature programs and understand the most important industrial TGA applications.

Key Takeaways

  • Understand the basic measurement principles of TGA
  • Learn the advantages of using different temperature programs and/or atmospheres
  • Discover the most important applications from different industries
  • Explore the utility of the many different results you can get by TGA

Dr. Angela Hammer, Application Specialist for Thermal Analysis, Mettler-Toledo

Angela Hammer studied chemistry, and during her dissertation at the Institute of Organic Chemistry at the Swiss Federal Institute of Technology in Z├╝rich, Switzerland, she specialized in the development of immobilized components in ion-selective electrodes based on polyurethane membranes. She then joined Sika Technology AG in Zurich Switzerland, as an analytical chemist. In 2007 she joined Mettler-Toledo AG and has worked there since as application specialist for thermal analysis. In her present position she uses, teaches and supports DSC, TGA, TMA and DMA instruments at the METTLER TOLEDO head office in Switzerland.
