Weboverall quality and interpretation of DSC results. BACKGROUND Differential scanning calorimetry (DSC) is a thermal analysis technique which measures the temperature … Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature … See more There are two main types of DSC: Heat-flux DSC which measures the difference in heat flux between the sample and a reference (which gives it the alternative name Multi-Cell DSC) and Power differential DSC … See more An alternative technique, which shares much in common with DSC, is differential thermal analysis (DTA). In this technique it is the heat flow to … See more Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample. Using this … See more • Chemical thermodynamics • Calorimetry • Endothermic • Exothermic • Forensic engineering See more The basic principle underlying this technique is that when the sample undergoes a physical transformation such as phase transitions, more or less heat will need to flow to it than the reference to maintain both at the same temperature. Whether less or … See more The result of a DSC experiment is a curve of heat flux versus temperature or versus time. There are two different conventions: exothermic … See more The technique is widely used across a range of applications, both as a routine quality test and as a research tool. The equipment is easy … See more
