Method
Differential Scanning Calorimetry
Differential Scanning Calorimetry (DSC) is a thermal analysis technique used to measure heat flows associated with physical or chemical changes in a material as a function of temperature or time. In a DSC measurement, both the sample and a reference are subjected to the same controlled temperature program, while the instrument continuously records the difference in heat flow between them.
This approach allows the precise detection of endothermic events, such as melting or glass transitions, and exothermic processes, such as crystallization or curing reactions. Because the heat flow is recorded directly under identical conditions, even subtle transitions can be quantified with high accuracy. These results are essential for quality control, material development, and research, enabling the prediction of product performance under real-world conditions.
With the DSC L63, advanced options such as Modulated DSC (MDSC) allow reversible and non-reversible processes to be distinguished, further improving data interpretation. The method is suitable for a wide range of materials, including polymers, metals, ceramics, pharmaceuticals and food products, offering reproducible and comparable results across diverse applications.
Functional principle of the DSC L63
The DSC L63 measures the heat flow difference between a sample and a reference material during a precisely controlled heating or cooling program. Both are placed in separate crucibles inside a temperature-controlled furnace and subjected to identical conditions.
Throughout the entire temperature cycle, the DSC L63 continuously records one key measured variable:
- Heat flow – Endothermic and exothermic events such as melting, crystallization, glass transitions, curing reactions or oxidation are detected by changes in heat absorption or release.
With its true heat flow design, high-performance silver furnace, and advanced electronics, the DSC L63 provides highly accurate, reproducible results. Optional Modulated DSC (MDSC) enables the separation of reversible and non-reversible processes, offering deeper insight into complex material behaviors.

DSC L63 explained - use, capabilities aad frequently asked questions
Modulated DSC
Differential Scanning Calorimetry (DSC) is an established method for analysing thermal transitions and reactions in materials. In classic DSC, measurements are taken at a constant heating rate, recording the entire heat flow generated by endothermic or exothermic processes. This provides reliable information about melting, glass transitions or crystallisation, for example.
Modulated DSC (MDSC) extends this principle: an additional sinusoidal temperature modulation allows the measured heat flow to be separated into reversible (e.g. glass transitions, melting) and non-reversible components (e.g. crystallisation, relaxation).
This makes it easier to differentiate between overlapping effects – a significant advantage for complex materials or weak transitions.
The precise determination of specific heat capacity (Cp) is particularly valuable in the study of polymers, composites and many others, as it reflects the material’s ability to store thermal energy.

Polymers
Polymers are used in countless applications – from packaging and automotive parts to aerospace and medical devices. To ensure reliable performance, understanding their melting behavior, glass transition temperature, crystallinity, curing characteristics and oxidation stability is essential, as these properties directly influence mechanical performance, processing behavior and long-term durability.
The LINSEIS DSC L63 enables precise and reproducible analysis of these key thermal properties across all polymer types – including thermoplastics, thermosets and elastomers. Whether for product development, quality control or material comparison, DSC measurements help optimize processing parameters, improve product stability and support the selection of the most suitable material for each application.
Application example: PET Granulate 1. Heating
The analysis of polymers is one of the main applications of DSC. Effects such as glass transitions, melting, and crystallization points are of interest and often challenging to detect. The new LINSEIS L63 DSC offers high resolution and sensitivity, making it an ideal instrument for this type of analysis. With its innovative design, it is now possible
to analyze important properties of the sample even during the initial heating of the PET granulate using the L63 DSC at a linear heating rate of 20 K/min. The curve shows a significant glass transition around 80 °C, followed by a melting peak at 246 °C.
Application example: PET Granulate 2. Heating
Depending on the cooling rate, the degree of crystallinity of the polymer changes significantly. During a subsequent heating run, cold crystallization can be observed with a linear heating rate of 20 K/min. The curve reveals a distinct glass transition at around 80 °C, followed by cold crystallization of the amorphous regions starting at approximately 148 °C and a melting peak at starting 230 °C. This allows the complete characterization of the sample with just two heating cycles.
