Differential Scanning Calorimetry and Heat Flow

Differential scanning calorimetry, or DSC, is a thermodynamic analysis method that tracks heat flow as temperature changes. It compares a sample material sealed in a pan with an empty reference pan. Both pans are exposed to the same temperature conditions.

The instrument records the energy differ...

Energy changes that occur during chemical reactions are defined by the term enthalpy, and are an important concept in thermodynamics. While enthalpy itself cannot be measured, the change in enthalpy in a system can be, and accounts for the energy transferred between a system and its environment during a chemical process at constant pressure.
