In DSC the heat flow between a sample and an inert reference is measured during a precisely controlled temperature program. The power required to maintain a constant heating rate is related to the heat capacity and any thermodynamic changes within the sample.
DSC has many applications but is the standard technique for studying polymer properties such as glass transition, melting & crystallisation.
The Modulated DSC option enables disambiguation of complex and overlapping thermal events.
