Differential Thermal Analysis / Thermogravimetric Analysis

Perkin Elmer Pyris Diamond

Differential thermal analysis (DTA) determines energy changes between a sample and reference material as the two are heated ata controlled rate. It is used to study the phase transitionsof material (magneticandnon-magnetic) Differential scanning calorimetry (DSC) measures the amount of energy required to establish zero temperature difference between a sample andareference material as the two are heated side by side at a controlled rate.
Thermogravimetric Analysis (TGA) is a technique whereby a sample is continuously weighed as it is being heated or cooled at a controlled rate.
Thermomagnetic measurements (TMA) can be performed in a range 300-1200 K applying a magnetic field (e.g 150 Oe) under Ar (or other gas) flow to determine Curie and other transition temperatures of magnetic materials.
