Thermal Analysis Techniques

This lecture covers various thermal analysis techniques, such as thermogravimetric analysis (TGA) used to measure mass changes in samples with temperature variations, differential thermal analysis (DTA) to measure temperature differences between samples, and differential scanning calorimetry (DSC) to quantify energy changes during phase transitions. The instructor explains how these techniques are applied in material characterization, including examples of TGA plots for calcium oxalate and CO2 adsorption studies, as well as DSC data interpretation for polymer heat capacity and crystallization. The lecture also touches on the importance of reference samples, instrument sensitivity, and the distinction between endothermic and exothermic transitions.
