There are various ways of carrying out thermogravimetric analyses, depending on the technical requirements. One possibility is to weigh each sample manually, put it into the drying cabinet or muffle furnace and then weigh it again. If several parameters need to be determined (for example, moisture and ash in flour), several furnaces with different temperatures (105 °C and 550 °C) are required as well as additional weighing. This method is fairly time-consuming.

A much more convenient and time-saving alternative is offered by thermogravimetric analysis instruments such as ELTRA’s TGA THERMOSTEP.

These analysers combine furnace and balance thus allowing for automated measurement of a variety of thermogravimetric parameters.  The user fills various samples into the ceramic crucibles and places them in the carousel inside the analyser where they are weighed by the integrated balance and automatically analysed. According to the selected program the samples are dried or reduced to ashes until they have the desired constant weight. No manual weighing is required. After the thermogravimetric analysis is finished, the relevant data can be directly transferred to a laboratory information management system (LIMS).

Coupled Techniques (mainly used in combination with MICRO TGAs): For enhanced detection and analysis of volatiles, thermogravimetric analysis (TGA) can be coupled with gas analysis techniques such as Fourier Transform Infrared Spectroscopy (FTIR), Mass Spectrometry (MS), or Gas Chromatography (GC). These techniques allow for the real-time analysis of gases evolved during the TGA run.

TGA-FTIR: Identifies functional groups in the evolved gases, providing insights into the composition of volatiles.

TGA-MS: Offers mass-to-charge ratio information, helping to identify the molecular structure of evolved gases.

TGA-GC: Separates the evolved gases, allowing for detailed compositional analysis.

The functional principle of thermal gravimetric analysis using the ELTRA THERMOSTEP can be summarized as follows:

• The initial sample weight is determined.
• The sample is heated to a temperature range of 40 °C to 1,000 °C.
• Based on the sample type, temperature, and atmosphere, the sample undergoes drying, oxidation, or loss of volatile components, leading to a reduction in weight (in rare cases an increasing of weight due to oxidation is possible).
• When the mass of the sample remains constant under the selected conditions, it is again weighed, and the mass change is documented.

An inert atmosphere, such as nitrogen or argon, is often used when the goal is to prevent oxidation or combustion of the sample. This environment is suitable for detecting the thermal decomposition products of the sample without interference from reactions with oxygen:

• the first mass loss at temperatures around approx. 100°C is most likely due to the evaporation of water or residual solvents within the sample or on its surface.
• at temperatures ranging from 200°C up to 600°C and sometimes even higher, thermal decomposition and release of volatile substances takes place.

An oxidative atmosphere (air or pure oxygen) is chosen when the interest lies in studying oxidative degradation or combustion products.

• In the presence of oxygen or air materials may undergo oxidation, whereby this can already take place with temperatures starting at 100°C. Above approximately 300°C, organic substances experience oxidation, leading to a rapid decrease in mass, a process known as combustion. This is characterized by the emission of CO2 and various gases, resulting from the oxidation of the organic elements.

It is important to note that the exact temperatures and phenomena observed depend on the specific material type being analysed and on the experimental conditions.
