TGA analysis – thermogravimetric analysis

(TGA ) Thermogravimetric analysisis a thermal analysis technique that measures the mass change of a sample as a function of temperature or time, under a controlled atmosphere. By monitoring these mass losses, it reveals key information about the composition and thermal behavior of a material.

What can TGA determine? Thermogravimetric analysis is used to quantify moisture and volatile compounds, assess thermal stability and degradation temperature , determine ash and mineral content, and study oxidation and decomposition phenomena . It is applicable to a wide variety of matrices: polymers and engineering materials, plant extracts , cosmetics, food products, and nutraceutical ingredients.

Which method and which couplings?
The analysis is based on thermogravimetric analysis (TGA/TGA), performed using a high-precision microbalance. To go further, TGA can be coupled with other techniques: TGA-FTIR or TGA-MS to identify the gases emitted during decomposition , or simultaneous thermal analysis (STA) combining TGA and differential scanning calorimetry (DSC). TGA is part of the family of thermal analysis methods, alongside DSC , DMA (dynamic mechanical analysis) , and TMA, which are often combined to fully characterize a material.

Related Analyses Depending on your objective, TGA can be usefully complemented by other services from our catalog: thermal degradation analysis , polymer characterization , or even deformulation when it comes to identifying the composition of a product. This analysis is particularly relevant to the polymers and materials , cosmetics , and nutraceutical sectors .
