TGA/DSC Simultaneous Thermal Analysis
TGA/DSC simultaneous thermal analysis integrates Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) in the same instrument to synchronously monitor mass changes (TGA) and heat flow changes (DSC) of samples under programmed temperature control. It is used to determine the glass transition temperature, cold crystallization, specific heat capacity, thermal stability, degradation rate, and chemical changes of test materials.
Principle of TGA/DSC Simultaneous Thermal Analysis
A technique for measuring the mass and heat flow of a sample as functions of temperature or time under programmed temperature control.
Instrument Model
