Applications:

Differential scanning Calorimetry (DSC) used to measure energy changes as a function of temperature or time. A typical graph is shown in Figure. Using this method it is probable to observe a number of features properties of a sample like fusion, crystallization, glass transition temperatures (T_g) as well as other thermo chemical reactions. DSC could also be used to study oxidation, as well as other chemical reactions. Glass transitions might occur as the temperature of an amorphous solid is rise. These transitions appear as a step within the baseline of the recorded DSC signal. This is because the sample undergoing a change in heat capacity; no formal phase modify occurs. Since the temperature rise, an amorphous solid will become less viscous. At a few point the molecules might acquire sufficient freedom of motion to spontaneously arrange themselves within a crystalline form. This is called as the crystallization temperature (T_c). This transition from amorphous solid to crystalline solid is an exothermic procedure and results in a peak in the DSC signal. Since the temperature rise the sample eventually reaches its melting temperature (T_m). The melting procedure results within an endothermic peak in the DSC curve. An ability to determine transition temperatures and enthalpies makes DSC an invaluable tool in producing phase diagrams for several chemical systems. The technique is hugely used across a range of applications, both as a routine quality test and as a research tool. The equipment is simple to calibrate, using low melting indium for instance, and is a rapid and reliable method of thermal analysis.
