TGA/ DSC

TGA/DSC is a thermoanalytical technique which measures heat flow and weight/mass change of materials as a function of temperature or time.

The technique can provide information about thermal stability, Oxidative stability and decomposition kinematics of materials. We can identify phase transitions, melting point, enthalpy, composition etc. of a material by utilizing this instrument. The technique have applications in understanding the behavior of a wide variety of materials including polymers, inorganic/organic chemicals, pharmaceutical drugs, composites and many more.

Working Principle

Thermo-Gravimetric Analysis (TGA)–The sample is heated in N2environment at a constant rate and the change in the weight of the substance is recorded as a function of temperature or time.

Differential Scanning Calorimetric (DSC)- The difference in heat flow required between the Sample and the reference to keep the temperature constant, is measured.
