The investigation of pharmaceutical substances by thermal analysis
Thermal Analysis is often used to investigate pharmaceutical substances. Polymorphism, pseudo-polymorphism, phase diagrams, stability, and purity determination can all be measured by thermal analysis. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterising such substances. The chief advantage is that properties can be measured as a function of the temperature or time over a wide temperature range, from –150 to 1600 °C.
In this webinar, we will show how thermal analysis is used to investigate pharmaceutical substances. We will present some typical examples measured by DSC, TGA, TMA or DMA.
Dr. Rudolf Riesen, Senior Applications Specialist, Mettler Toledo AG
After obtaining a Ph.D. in chemical engineering at the Swiss Federal Institute of Zurich (ETH) in 1978, he joined Mettler Toledo first working in R&D on the development of the microprocessor controlled thermal analysis and reaction calorimeter RC1 and later in worldwide application support for TA and RC1. 1992-1997 Dr. Riesen was appointed market support group manager for thermal analysis and rheology.
