概要	Differential Scanning Calorimetry (DSC) is a thermal characterization technique that measures the heat flow required to maintain a sample and an inert reference at the same temperature while both are heated or cooled. Invented by Watson, O'Neill, and colleagues in 1964, DSC directly quantifies enthalpy changes during phase transitions, crystallization, melting, and chemical reactions. It is the standard tool in materials science, chemistry, and pharmaceutical research for determining thermodynamic properties, thermal stability, and kinetics of thermal transitions.	Thermogravimetric Analysis (TGA) is a thermal characterization technique that continuously measures mass loss or gain of a material as a function of temperature (or time at constant temperature). Developed systematically by William Wendlandt and colleagues in the 1960s, TGA identifies thermal transitions (evaporation, decomposition, oxidation, reduction) and quantifies composition of polymers, pharmaceuticals, ceramics, and other materials. The derivative signal (DTG) highlights transition temperatures. When combined with gas analysis (MS, FTIR), decomposition products are identified.
