TGA analysis provides information regarding the weight loss of the uncalcined material at different temperatures. How much weight loss is observed depends on the nature of the material used for analysis. The obtained data were plotted in origin. The X-axis shows the temperature, and the Y-axis shows weight loss. Copy the data from the file and plot it in origin.

Dear Asima Zahoor ,

Perhaps the attached document might be useful for you.

If you have any doubts after checking it out, feel free to ask!

You can start reading some books or dedicated papers to thermal analysis. In fact, TGA is in many cases associated to DSC or DTA (there are also combined instruments) to have more information about the analysed sample

Thermal analyses give information about your material's thermal behaviour. If you conflict the curves of TG-DTG-DTa, you can understand the mechanism steps. You can identify the thermal behaviour by looking at the initial and final temperatures. In TG curves you can determine the mass losses.

If you search on "your material thermal behaviour" on google scholar, you can find related articles and also you can understand it comprehensively by reading them.

Actually TGA provides you the thermal status of a subjected samples by following the mass loss due to the applied heat within a particular range of temperature. Meanwhile the subjected samples undergoes dehydration, decomposition or degradation reaction due to the removal of moisture/water and other lower molecular weight components from the structure.

For a better understanding you can read the following articles which could be beneficial to you.

First, you need to know the variables used, such as the amount of materials tested, scan rate, starting and end temperature of the measurement, purge gas and flow rate. Then, you have to understand the weight drop associated with the properties of the materials tested. In general, the initial weight loss is due to surface wet demonstrated by a gradual Wt loss; followed by a sudden Wt loss if applicable, suggesting a bonded water or organic solvent molecules; then finished by a large Wt loss near the end, indicating decomposition of the materials tested.
