What kind of data are you trying to get? for TGA analysis most of the chemical kinetics can be calculated through mass and temperature change. check my profile where you can find three papers explaining step by step how to make these kind of analysis.

If you determined the reaction model previously (for example, using combined kinetic analysis), you can plot f(alpha)/f(0.5) to trade with ideal models. I recommend an article that may be of use to you

You can use my software - thinks.chemphys.ru - to perform thiskind of analysis

Hello Tomasz,

You are right - the best way to help you is first to see your data and try to analyze them. If you are still interested email me data, preferably in an Excel book. A data set should be presented by the table that includes {time}, {temperature}, {TG}+

sample mass, heating rate. You can email your data via [email protected]

Regards

It is a follow-up to the question and to my previous answer, though somewhat delayed. As Tomasz provided me with his data I was able to analyze the case. The results are presented in CISP Newsletter 17 Example of kinetic analysis of complex thermogravimetry data, DOI:10.13140/RG.2.2.16819.35364
