Thermogravimetric analysis (TGA) is an analytical technique used to determine a material's thermal stability and its fraction of volatile components by monitoring the weight change that occurs as a sample is heated at a constant rate.

What are the applications of TGA?

A TGA can be used for materials characterisation through analysis of characteristic decomposition patterns. It is an especially useful technique for the study of polymeric materials, including thermoplastics, thermosets, elastomers, composites, plastic films, fibres, coatings, paints, and fuels.

What are the types of thermogravimetric analysis?

There are three types of thermogravimetric analyzers: suspension system, top-loading system and horizontal system.

What is thermogravimetric analysis and what kind of information TGA machine can give?

Thermogravimetric analyzers measure changes in mass or weight in response to increases in temperature or time. These kinds of measurements can give valuable information about a material's thermal stability, response to oxidation, composition, decomposition kinetics, moisture content, and more.

What are the main drawback of TGA experiment?

COUPLED THERMAL ANALYSIS TECHNIQUES TGA has thus proven to be an excellent quantitative technique but less suitable for specification. This drawback can be eliminated if the components which are causing the mass losses detected, are also analysed simultaneously, the so-called evolved gas analysis (EGA).

How does TGA analysis work?

How TGA works. In thermogravimetric analysis (TGA), a sample is continually weighted while heating, as an inert gas atmosphere is passed over it. Many solids undergo reactions that evolve gaseous byproducts. In TGA, these gaseous byproducts are removed and changes in the remaining mass of the sample are recorded.

What are two main techniques for thermal analysis?

Explanation: The two main thermal analysis techniques are thermogravimetric analysis known as TGA which measures the change in weight with temperature and Differential thermal analysis known as DTA which detects changes in heat content.

What is DSC used for?

Differential scanning calorimetry (DSC) is the most frequently used thermal analysis technique alongside TGA, TMA and DMA. DSC is used to measure enthalpy changes due to changes in the physical and chemical properties of a material as a function of temperature or time.
