WebThe DSC and TMA often give results that differ from one another by 5-10˚C when used to test a polymer. Moreover, some polymers are more amenable to DSC (epoxies for instance) or to TMA (i.e. some of the first generation polyimides such as Kerimid 601), because the transition is easier to observe using one technique over the other. For example if a WebProtein stability is important in many areas of life sciences. Thermal protein unfolding is investigated extensively with various spectroscopic techniques.
