Your needs: perform thermogravimetric analysis (or TGA analysis) of your materials

What is thermogravimetric analysis?

Thermogravimetric analysis is a thermal analysis technique used for materials characterization. Also known as TGA analysis, this method makes it possible to analyze materials, particularly polymers, by identifying their behavior as a function of temperature.

By gradually heating a sample, TGA analysis reveals the material’s behavior under heat and identifies key properties such as thermal stability and composition.

Understanding how a material reacts to heat enables us to better anticipate its performance, stability and evolution over time.

What is TGA analysis?

Thermogravimetric analysis (TGA analysis) is a technique that measures changes in the mass of a material as a function of temperature. By heating a sample, its weight loss or gain is observed, enabling processes such as decomposition, oxidation or volatilization to be analyzed.

This method is essential for assessing the thermal stability, composition and thermal reactions of materials such as polymers, plastics and paints.

 In a TGA laboratory, precise measurements are conducted to ensure accurate analysis of material properties.

Why use TGA thermogravimetric analysis?

TGA analysis involves measuring the change in mass of a sample when it is heated. The results obtained from TGA analysis can be used to identify the evaporation, desorption, decomposition or combustion temperatures of the material under study. This analysis can be used to identify thermal properties such as phase transitions, thermal stability, chemical composition, surface mechanics and reactivity.

This method is therefore extremely useful for understanding the thermal degradation mechanisms of polymers, for example. It is widely used in industry to improve product quality and stability, as well as for research into new materials, particularly in the plastics industry. By utilizing TGA analysis, companies can ensure their materials meet required standards and perform reliably under thermal stress. The FILAB laboratory can offer you its expertise in TG analysis of your materials to obtain the results you need.

ATG

Our technical resources: TGA and analytical coupling

Analytical coupling involves combining ATG with one or more other analysis techniques to obtain additional information about the sample under study. The principle is based on the simultaneous use of different methods to analyse the same samples under the same conditions, allowing a more in-depth analysis of the properties and reactions of the sample when subjected to temperature variations. This approach enhances the capabilities of a TGA laboratory by providing comprehensive insights into material behavior.

ATG analysis can be coupled (ATG-MS and ATG-FTIR) with other analytical methods:

Mass Spectrometry (MS): This allows the analysis of gases emitted during the thermal decomposition of the sample. This TGA-MS coupling can identify the composition of the gaseous products released. Such detailed analysis is crucial for understanding complex decomposition processes in materials. 

Fourier Transform Infrared Spectroscopy (FTIR), which enables analysis of the gases and vapours emitted. ATG-FTIR coupling provides information on the chemical structure of the products released.

This technique is particularly valuable in identifying specific compounds evolved during thermal analysis.

Technical characteristics of TGA analysis

ATG analysis is highly sensitive and accurate in detecting changes in mass. This makes it possible to identify mass losses due to processes such as dehydration, decomposition, oxidation or other chemical or physical reactions.

In addition, the ATG offers precise temperature control, enabling experiments to be carried out under a wide range of thermal conditions. Analyses can also be carried out under different atmospheres (inert, oxidising, reducing, etc.), which is essential for studying the specific behaviour of materials in your reference environments.

Other laboratory thermal analysis

What is a thermogravimetric analysis (or TGA)?

Thermogravimetric analysis (TGA) is an analytical technique used to measure physical or chemical changes in the weight of a sample as its temperature varies over time. It measures the mass of a sample while it is heated, cooled or held at constant temperatures. This information can be used to determine how various factors, such as heat, humidity and exposure to certain chemicals, affect the composition and stability of the material. It is commonly used in materials research and quality control applications. Thermogravimetric analysis can also be used to identify unknown substances by recording their rate of mass change with temperature. By plotting this data, researchers can obtain valuable information about the composition of the sample and its stability. It is an important tool for many industries, including aerospace, medical device manufacturing and the chemical industry. It can be used to assess the effects of long-term storage or use of certain materials, enabling engineers to create better products and optimise processes.
