Hi, Surakanti Srinivas Reddy!

It is quite difficult to say what to expect if you do not tell us what kind of sample you have investigated. Where did you measure your sample? Do they not support you with any analysis?

Here is a link for a brief introduction which may be helpful for you:

Hello.

You can search similar TGA guide.

Thank you so much for your answers. Can any one please tell me which software should be used to get the information about onset temperature?

Thank you Mr. Daniel, I have investigated carbon black samples but I don't know how to fit it and get onset temperature. If time permits, please tell me which software is useful for it.

Surakanti Srinivas Reddy,

you can use, for example, the MagicPlot programm (https://magicplot.com/downloads.php).

You need to create the table with your data (temperature-TGA signal). After plotting the curve you can differentiate it and so you will find onset and endset temperature. I added screenshots for clarity.

Dear Anna Matveyeva ,

Thank you so much for your answer.

Surakanti,

I would recommend using the Netzsch Proteus software, especially if you are planning on performing further TGA studies. It has an option of 'auto plot' which will provide consistent values for onset mass loss steps etc and will accept several file types.

review in researchgate some of my publications on thermodegradation

Can we get free version of Netzsch Proteus software for academic purpose, Mr. Thomas Hope?

I’m not sure, you would have to contact a netzsch representative. I have USA and European contacts but nothing else. Where are you based?
