The Differential Scanning Calorimeter (DSC) measures the heat flow to or from a sample under controlled heating conditions. A small amount of sample (1-10 mg) is contained within a closed crucible and placed into a temperature controlled furnace. A second crucible is used as a reference. The sample is then heated by the temperature controlled furnace. The most commonly used method of temperature control is dynamic (or scanning) mode which utilizes a constant heating rate. Another mode of operation is isothermal mode and is used to maintain a constant temperature. In both of these modes, the heat flow to or from the sample is measured as a function of time and temperature.
