Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) are well-established method for the characterization of active pharmaceutical ingredients, excipients, or formulations. DSC allows for the determination of fundamental physicochemical properties such as melting/crystallization temperatures, heats of fusion or glass transition temperatures. TGA provides information about thermal stability of chemicals, evaporation phenomena, and pyrolysis behavior. Rheology perfectly complements the analytical equipment of your laboratory and allows, among many other applications, for the specification of a suitable viscosity for different pharmaceutical products. Using selected examples, the webinar introduces the thermal analysis methods DSC and TGA as well as rotational and capillary rheology and provides a brief overview of the broad application range of the methods.
