Method
Differential Scanning Calorimetry (DSC) is a powerful analytical technique widely utilized in materials science, chemistry, and related fields to measure thermal transitions in materials. The heat-flow DSC system, a common variant, operates by directly measuring the heat flow associated with material changes as a function of temperature and time.
Measuring Principle of Differential Scanning Calorimetry
The measurement principle of Differential Scanning Calorimetry (DSC) is based on monitoring the difference in the amount of heat required to raise the temperature of a sample and a reference material at the same rate. Because the sample and reference are exposed to identical temperature conditions, any difference in heat flow between them is meaningful and thus measured. This difference indicates that the sample is undergoing physical or chemical changes such as melting, CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization or chemical reactions that either absorb or release heat.
A DSC measuring cell consists of a furnace and an integrated heat-flux sensor with designated positions for the sample and reference pans.
The DSC instrument records these heat flow differences as the temperature changes, providing a detailed profile of the sample´s thermal properties and transitions.
The DSC systems are based on relevant instrument and application standards, e.g., ISO 11357, ASTM E793, ASTM D3895, ASTM D3417, ASTM D3418, DIN 51004 and DIN 51007.

TM-DSC module software extension for temperature-modulated DSC tests:
Temperature-modulated DSC (TM-DSC) is a DSC technique whereby a sample is subjected to a superposition of a linear and a periodic temperature program. Temperature-modulated DSC enables the separation of overlapped DSC effects by calculating the reversing and non-reversing signals. Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.Glass transitions can therefore be well separated from, for example, ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermal Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing, Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, evaporation, RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation or cold-CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization processes in a single TM-DSC test. The DSC 500 Pegasus® is the only DSC which allows for TM-DSC tests up to 1650°C. Nearly all available furnaces in combination with different DSC sensors are suited for such tests. It is totally based on a software solution. The NETZSCH TM-DSC solution improves separation of time-dependent events from the total heat flow.
Peak Separation permits accurate separation and evaluation of overlapping transitions.
PeakSeparation allows for the presentation of experimental data in the form of the additive overlapping of peaks. This program offers different curve types such as Pearson, Gauß, Cauchy, pseudoVoigt, Fraser-Suzuki, modified Laplace and Pearson. With it, the experimental data is fitted as an additive superposition of peaks.
Purity Determination is a program for determining the purity of a material through analysis of the DSC melting peak.
This advanced temperature calibration, which conforms to international standards, is not only temperature dependent, but also heating rate dependent. This software option is especially beneficial for temperature accuracy when different heating rates are used in the same measurement.
Prediction of Material Behavior and Reaction Processes:
Materials with accurately defined properties can be transformed into other substances with other properties by chemical reactions. The reactions can take place within a fraction of a second – like in the case of explosions – or take hundreds of thousands of years, as is the case in the formation of minerals. This is because processes like decomposition, curing, crystallization and sintering of materials are dependent on time and temperature. Knowledge about the speed of these processes is therefore important in order to simulate material behavior or optimize a process.
Kinetics, also called reaction kinetics or chemical kinetics, studies the rate of chemical processes and allows for determination of reaction rates. It also takes the factors, which control these reactions, into account.
NETZSCH Kinetics Neo software is used to analyze chemical processes. The software allows for the analysis of temperature-dependent processes. The result of such analysis is a kinetics model or method correctly describing experimental data under different temperature conditions. Use of the model allows for predictions of a chemical system’s behavior under user-defined temperature conditions. Alternatively, such models can be used for process optimization.
The software can analyze different types of thermal curves that depict the changes in a given material property measured during a process. Potential data sources include studies using Differential Scanning Calorimetry (DSC), Thermogravimetry (TGA), Dilatometry (DIL), Dielectric Analysis (DEA), Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.Accelerating Rate Calorimetry (Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®), Rheology and Viscosity (Torque).
