(The relationship between temperature and sample mass)


What Is It?

Thermogravimetric Analysis (TGA) is an analytical technique which measures the mass of a sample as a function of time and/or temperature.

Why Should I Use It?

Through interpretation of plots, we can determine degradation points, amount of plasticizer oils, proportions of different polymers in blends, oxidation onset.
We present the sample’s changes in a graph which shows the relationship between temperature and sample mass over the course of the analysis, which can help you understand it clearly.

What Do I Get Out of It?

Plots showing mass loss (or in some cases, mass gain) as a function of time or temperature yield information on the composition and changes in the sample.
