Techniques
Calorimetry

Calorimetry is used to study the thermal properties of materials and devices.

Differential Scanning Calorimetry (DSC) determines the change in heat required to increase the temperature of a sample relative to a reference sample. Plots of heat flow against temperature detect glass transitions, crystallisation and melt events. DSC plays a key role in the polymer and pharmaceutical industries to study curing, cross-linking and an-isotropy of drugs.

Thermogravimetric analysis (TGA) determines weight changes with temperature and is employed to study degradation temperatures, moisture content and the amount of inorganic and organic compounds in materials.
