Specific Heat Measurement
Heat Capacity Measurement by DSC (Differential scanning calorimetry)
DSC measures endothermic and exothermic reactions caused by changes in the state of the sample by measuring the temperature of the reference material and the sample while applying a constant heat.
DSC is able to observe not only simple thermal reactions such as melting but also structural phase transitions and crystallization. Therefore, DSC is widely used to evaluate the physical properties of polymers, organic materials, metals and ceramics.
