A differential scanning calorimeter is used to heat or cool the material over a temperature range, while measurements of heat flow are made. Typically, the material is heated rapidly to its molten state and data is collected in the cooling mode to 40°C, at a constant rate of 20ºC/min. First, a baseline is run for the desired heating or cooling conditions of the scan. Next the specimen is placed into the DSC apparatus and the scan is repeated. Specific heat obtained from subtracting the two curves.
The scan can also consist of collecting data while heating the material to its molten state. The rate of heating or cooling can be specified.
