Thermogravimetry Analysis and Differential Scanning Calorimetry Analysis (TGA/DSC)

Main Applications of TGA and DSC Analysis

 

(TGA) THERMOGRAVIMETRY ANALYZER

• Thermogravimetric Analysis or TGA is a type of testing that is performed on samples to determine changes in weight in relation to changes in temperature. Such analysis relies on a high degree of precision in three measurements: weight, temperature, and temperature change. As many weight loss curves look similar, the weight loss curve may require transformation before results can be interpreted. A derivative weight loss curve can be used to tell the point at which weight loss is most apparent. Again, interpretation is limited without further modifications and deconvolution of the overlapping peaks may be required. 

 

 

(DSC) DIFFERENTIAL SCANNING CALORIMETER

• DSC measures endothermic and exothermic transitions as a ftemperature temperatur. Used to characterize polymer, pharmaceuticals, food/biological, organic chemicals and inorganics. Transitions measured include eg, melting, crystallization, curing and cure kinetics, oxidation and heat capacity.
