DSCbasierte

DSCbasierte is a term used in German-language texts to denote methods or analyses based on differential scanning calorimetry (DSC). In English, the term is commonly written as DSC-based. DSC-based approaches measure heat flow to a sample and a reference under controlled heating or cooling to study thermal events in materials.

DSC records heat flow as a function of temperature or time. Thermal transitions appear as endothermic or exothermic features on a thermogram. Key markers include the glass transition temperature (Tg), crystallization temperature (Tc), and melting temperature (Tm); the corresponding enthalpies yield information on content such as crystallinity and phase content. Modulated DSC (MDSC) is a variant that helps separate overlapping processes by dividing the heat signal into reversing and non-reversing components.

Data processing for DSC-based analyses typically includes baseline correction, instrument calibration, and peak integration. DSC data contribute to determining crystallinity, phase behavior, and thermal stability, and can provide kinetic information in isothermal experiments or when kinetic models are applied to nonisothermal data.

Applications span polymers, pharmaceuticals, foods, and coatings. DSC-based methods support material design, process optimization, quality control, and stability assessment by revealing how materials respond to temperature changes, how processing affects structure, and how heat treatment influences performance.

Limitations include sensitivity constraints, baseline drift, and dependence on heating/cooling rates. Proper sample preparation and calibration are essential, and DSC-based results are most informative when complemented by other techniques such as thermogravimetric analysis or dynamic mechanical analysis.
