Thermal Analysis is a useful tool for investigating pharmaceutical substances for effects such as polymorphism, purity and composition, phase shifts, and stability. The four main techniques of DSC, TGA, TMA, and DMA are ideal for carrying out these investigations over a wide temperature range, from -150 to 1600 °C.
