Thermogravimetric Techniques for the Characterization of Volatiles and Decomposition Products

Evolved gas analysis
Evolved gas analysis

Evolved gas analysis (EGA) is a method used to study the nature of volatile products released by a substance as it is heated. This can be carried out using many different techniques and types of equipment.

In this webinar, we explain the principles involved in EGA and describe the benefits and limitations of the four TGA-EGA techniques:

  • MS (Mass spectroscopy)
  • FTIR (Fourier-transform infrared spectroscopy)
  • GC/MS (Gas chromatography/Mass spectroscopy)
  • Micro GS/MS

We will illustrate the use of each technique using several different application examples.

What Is a TGA-EGA System?

Evolved gas analysis is commonly performed by coupling a thermogravimetric analyzer to a mass spectrometer, or a Fourier-transform infrared spectrometer, to create a TGA-EGA system. The TGA instrument records the loss in mass of a sample as it is heated, while the spectrometer provides information about the gaseous products released due to processes such as evaporation, desorption, decomposition, and chemical reactions.

 

Industries and Applications

EGA can be used in practically all industries from automotive to chemicals, plastics, and pharmaceuticals. There are many, diverse applications such as the detection of residual solvents in pharmaceutical ingredients, the pyrolysis of PVC, and determining the composition of unknown rubbers.
