TGA, TGA-FTIR and ATG-MS analysis in a laboratory

Your needs : to analyze a substance or a material using TGA technics

TGA thermogravimetric analysis are used to determine the mass lost by a material depending on how badly it is degraded in precise thermal conditions (thermal cycles)

By coupling this technique with FTIR (Fourier Transform Infrared Spectroscopy) or with mass spectrometry (TGA-MS) it is possible to chemically identify the loss of mass, of released gasses or of degradation products that appear during the thermal cycle.

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.

ATG analysis can provide useful information about the composition, structure and stability of a material. It can also be used to determine how different environmental factors affect the properties of the sample. This data can be invaluable when creating materials for aerospace or medical device manufacturing. By understanding the physical or chemical changes that occur over time, engineers are better equipped to design more durable and reliable products.

Thermogravimetric analysis (TGA) is a valuable tool that can be used to characterise materials, identify unknown substances and monitor the stability of samples. It can also be used to measure reaction kinetics, moisture content and other properties.

TGA-FTIR is an analysis technique widely applied in the laboratory, combining thermogravimetry and infrared spectrometry. The technique is used to study the chemical composition and thermal properties of different materials.


Ultimately, the TGA-FTIR analysis combines two key measurements. The thermogravimetric analyzer performs quantitative measurements, while the infrared spectrometer enables substances to be identified. In this way, TGA FTIR analysis provides precise, detailed results on the composition of gases emitted during the various stages of the process and during thermal modification. Two measurements are carried out: weight analysis and gas identification.


Coupling thermogravimetric analysis methods with FTIR analysis offers many advantages. All the gases from the ATG then pass through the FTIR, where the molecules are identified according to their absorption of infrared light wavelengths.

This analysis method is capable of providing information on the thermal modifications of organic and inorganic molecules, as well as their identification. Industries that can benefit from a TGA-FTIR analysis include chemicals, pharmaceuticals, cosmetics, food, petrochemicals and many others.

This technique is useful in many industrial applications, such as the characterization of polymers, composite materials and pharmaceuticals.

In short,TGA- FTIR is an advanced analytical method for ensuring product quality and safety, as well as improving the performance of industrial processes.
