Understanding the gases released from a sample during heating can provide valuable insights into material composition and behavior. This webinar introduces the principles and benefits of evolved gas analysis and demonstrates how it can support the investigation of volatile compounds and decomposition products.
Register today to explore TGA-EGA techniques, discover practical applications, and ask our experts your questions during the live Q&A.
What Is a Hyphenated TGA-EGA System?
Thermogravimetric analysis (TGA) measures changes in the mass of a sample as a function of temperature or time. TGA alone, however, cannot identify the gaseous products evolved during a measurement.
Evolved gas analysis is performed by coupling a TGA instrument with a gas analysis system, creating a combined TGA-EGA system. This allows evolved gases to be analyzed online and correlated with thermal events such as evaporation, desorption, decomposition, and other chemical reactions.
The main techniques used for TGA-EGA include:
- MS (mass spectrometry)
- FTIR (Fourier-transform infrared spectroscopy)
- GC/MS (gas chromatography–mass spectrometry)
- Micro-GC/MS
The additional information provided by TGA-EGA supports a better understanding of material composition and behavior, helping inform decisions in laboratory and production environments.
Industries and Applications
EGA is used across many industries where understanding evolved gases can be critical, including automotive, chemicals, plastics, and pharmaceuticals. Applications are diverse, such as detecting residual solvents in pharmaceutical ingredients, studying the pyrolysis of PVC, and determining the composition of unknown rubbers.
