TGA-FTIR is a commonly used thermal analysis technique

TGA-FTIR is a commonly used thermal analysis technique, which is mainly used to study the thermal stability and decomposition of materials. The basic steps of the TGA-FTIR analysis are as following,

1, Sample preparation:

- Select the sample to be tested, making sure that the sample volume is enough for the test.

- The sample should be properly processed, such as crushing, mixing etc. to ensure its homogeneity.

2, TGA analysis:

- Place the processed sample into the TGA.

- Set parameters such as heating rate, maximum temperature, etc.

- Start the TGA and record the mass loss of the sample as the temperature changes.

3, FTIR analysis:

- During the TGA analysis process, the gases produced by sample decomposition are introduced into the FTIR for real-time analysis.

- Collect the FTIR spectrogram of the gas components produced by sample decomposition at different temperatures.

4, Data analysis:

- Analyze the TGA curves, determine the thermal stability, decomposition temperature and decomposition steps of the samples.

- Combined with FTIR spectral data, the gas components produced during sample decomposition can be identified to further understand the thermal decomposition mechanism of the sample.

Through the above analysis, we can fully understand the thermal stability and decomposition behavior of the samples, which provides important reference information for the selection, development and application of materials.
