Analytical objectives of thermogravimetric analysis TGA
Thermogravimetric analysis (TGA) is used to characterize the thermal behavior and composition of materials in order to meet the following objectives:
- determine characteristic temperatures (evaporation, decomposition, combustion)
- quantify mass losses (water, solvents, volatile compounds)
- assess composition (fillers, residues, organic/mineral fraction)
- analyze the mechanisms and kinetics of thermal degradation
- compare materials or batches in quality control
Our technical resources: TGA and analytical coupling
Le couplage analytique implique la combinaison de l’ATG avec une ou plusieurs autres techniques d’analyse pour obtenir des informations complémentaires sur l’échantillon étudié. Le principe est basé sur l’utilisation simultanée de différentes méthodes pour analyser les mêmes échantillons sous les mêmes conditions, permettant ainsi une analyse plus approfondie des propriétés et des réactions de l’échantillon lorsqu’il est soumis à des variations de température.
L’ATG peut être couplée (ATG-MS et ATG-FTIR) avec d’autres méthodes analytiques :
with Mass Spectrometry (MS), which makes it possible to analyze the gases emitted during the thermal decomposition of the sample. This TGA-MS coupling can identify the composition of the released gaseous products.
Thus, coupled TGA significantly enriches thermogravimetric analysis by adding detailed chemical dimensions to the mass change data.
The advantages of TGA
Precision and sensitivity of TGA analysis
Thermogravimetric analysis (TGA) stands out for its high sensitivity and precision in detecting mass changes.
It is particularly useful for identifying mass losses related to phenomena such as dehydration, decomposition, oxidation, or other chemical and physical reactions affecting materials.
Control of analysis conditions
TGA offers precise thermal control, making it possible to carry out analysis across a wide range of temperatures.
It also makes it possible to adapt the analysis atmosphere (inert, oxidizing, reducing, etc.) according to industrial constraints, in order to study the behavior of materials under their real operating conditions.

FAQ
Yes. ATG (Thermogravimetric Analysis) and TGA (Thermogravimetric Analysis) refer to exactly the same technique. The former is the French acronym, the latter the English one. In both cases, the aim is to observe the change in mass of a sample as a function of temperature or time.
There are three commonly used thermogravimetric analyses: TGA, TGA-MS, and TGA-FTIR. Each of these analysis types has its own advantages and disadvantages, as well as a range of common applications and use cases.
Differential thermal analysis (TGA), also known as thermogravimetric analysis, is a commonly used materials characterization technique for studying the thermal properties and stability of samples. There are two types of coupled TGA analysis that can provide more precise information on sample characterization:
- TGA-MS (mass spectrometry) enables the identification of gases released during thermal decomposition.
- TGA-FTIR (Fourier-transform infrared spectroscopy) enables the identification of solid decomposition products. By identifying each specific component in complex mixtures, these different TGA analyses offer greater accuracy and a better understanding of materials.
By coupling this TGA technique with FTIR (Fourier-transform infrared spectroscopy, FTIR) or mass spectrometry (TGA-MS), it is possible to chemically identify mass losses, released gases, or degradation products during the thermal cycle.
Performing thermogravimetric analysis (TGA) in the laboratory provides precise information on the composition, structure, and thermal stability of a material.
This TGA expertise is particularly useful for:
- quality control of raw materials and finished products
- identification of unknown materials
- study of thermal behavior and degradation mechanisms
TGA analysis is therefore widely used in demanding industrial sectors that require detailed materials characterization.
ATG analysis applies to many materials: polymers, composites, chemicals, powders or solids. At the FILAB laboratory, our ATG equipment is adapted to each matrix.
Thermogravimetric analysis is a commonly used method for identifying the quantity of a substance and its nature, based on the change in its mass as a function of temperature.
For interpreting the results, it is essential to know the different stages of the thermal degradation of the substance being analysed and to determine the transition temperatures reached throughout the mass change curve.
With a good understanding of the key principles, thermogravimetric analysis can provide valuable information to help optimize processes, evaluate materials and identify degradation mechanisms.
Thermogravimetric analysis is a common materials analysis method. It is especially favored in the chemical and pharmaceutical industries.
Common applications of thermogravimetric analysis include assessing the thermal stability of polymers, characterizing the combustion processes of organic materials and determining the decomposition mechanisms of biodegradation compounds.
The results of these analysis are valuable for understanding material properties and their optimal use in industrial applications.
Coupling Thermogravimetric Analysis (ATG) with other analytical techniques offers multiple advantages.
- Comprehensive analysis: The coupling provides an overview of the physical and chemical changes occurring in the sample.
- Gas identification: Coupled techniques can identify the gases released during thermal decomposition.
- Understanding reactions: It helps to understand degradation mechanisms and chemical reactions occurring at different temperatures.
Thus, coupled ATG significantly enriches thermogravimetric analysis by adding detailed chemical dimensions to mass change data.
The results obtained by thermogravimetric analysis (TGA) make it possible to identify the evaporation, desorption, decomposition, or combustion temperatures of the material studied. This analysis then makes it possible to identify thermal properties such as: then
- phase transitions
- thermal stability
