Differential Scanning Calorimetry (DSC) is a thermoanalytical instrument in which the difference for heat required to increase temperatures of a sample and a reference is measured as a function of temperature, which is usually programmed to change linearly as a function of time. It is frequently used to measure the latent heat of Phase Change Materials (PCM). In operation, an empty pair of aluminum or copper pan and lid is usually used as the reference and the sample is placed in another pair of pan and lid with the same material and weight as the reference, so that the heat flow to the reference is cancelled in software, and information of heat flow to the sample is collected. The result of a DSC experiment is a curve of heat flux versus temperature or time, and the integration of phase transition peak area on the curve indicates the latent heat of the sample.
The DSC-600 Differential Scanning Calorimeter is a powerful instrument that measures the heat absorbed or released as a function of time or a controlled temperature profile. Data collected with DSC-600 is analyzed with Infinity Pro thermal analysis software.
