Membrane Characterisation Equipment

Thermal Analysis: Differential Scanning Calorimetry

DSC 

Differential Scanning Calorimetry (DSC) measures the amount of energy absorbed or released by a sample when it is exposed to a temperature change. This provides quantitative and qualitative data on endothermic and exothermic processes.

DSC is used to measure melting/crystallization behaviour, solid-solid transitions, polymorphism, degree of crystallinity, glass transition temperature, cross-linking reactions, oxidative stability, purity determinations, specific heat capacity and thermokinetics.

Various crucibles (pans) are available. A suitable pan needs to be chosen to avoid reactions with samples and with regard to the temperature range of the measurement.

Various chamber atmospheres are available: nitrogen, oxygen, air, argon, vacuum or a specific gas mixture.
