Simultaneous TGA/DSC
Simultaneous TGA/DSC is a powerful combination in which both the TGA and the DSC curves are obtained in the same run. The figure below shows the TGA and DSC curves for the dehydration of CuSO4 * 5H2O measured in a simultaneous TGA/DSC experiment. The weight loss steps in the TGA curve can be clearly correlated with the DSC peaks.
Instrument specifications and sample requirements:
TGA/DSC
Ideal Sample Weight: 10 – 50 mg
Temperature Accuracy: +/- 1 ˚C
Heat Flow Accuracy: Better than +/- 2%
Recommended Heating rate*: 20˚C /min
Temperature Range: Ambient to 1500 ˚C
* Lower and higher heating rates are also possible and should be discussed with the lab for each specific set of samples.
