Method
Differential Scanning Calorimetry
The HDSC L62 is a high-performance DSC designed to measure heat flows linked to physical and chemical changes in materials over a wide temperature range from −150 °C to 1750 °C. In each measurement, both the sample and a reference are exposed to the same precisely controlled heating program, while the instrument continuously records the difference in heat flow.
This principle enables the accurate detection of endothermic events such as melting, glass transitions, polymorphic transformations, or volatilization, as well as exothermic processes like crystallization, oxidation, or curing reactions. Thanks to its high calorimetric sensitivity, short time constants, and excellent baseline stability, even subtle transitions can be reliably quantified.
The vacuum-tight design allows operation under high vacuum (up to 10⁻⁵ mbar), pressurized conditions (up to 5 bar), and controlled atmospheres, ensuring reproducibility under real-world conditions. Coupling options with MS, FTIR or GCMS further expand analytical capabilities, providing detailed insights into evolved gases during reactions.
With exchangeable DSC and DTA sensors (Types E, K, S, B, C) and optional automation via a 42-position sample robot, the HDSC L62 combines flexibility, precision, and efficiency. It is ideally suited for applications in polymers, metals, ceramics, pharmaceuticals, building materials and food, supporting both advanced research and routine quality control.
Functional principle of the HDSC L62
The HDSC L62 records 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 within a high-stability furnace and are subjected to identical conditions.
Throughout the entire temperature cycle, the instrument continuously measures heat flow, enabling the detection of endothermic events such as melting, glass transitions, enthalpic recovery, or polymorphic transitions, as well as exothermic processes like crystallization, oxidation, or curing reactions.
With its high calorimetric sensitivity, short time constants, and condensation-free chamber, the HDSC L62 provides excellent resolution and baseline stability. The vacuum-tight design supports measurements under high vacuum, pressurized, or controlled atmospheres, while optional coupling to MS, FTIR, or GCMS adds valuable insight into evolved gases.
Thanks to its modular concept with interchangeable DSC and DTA sensors and an optional 42-position sample robot, the HDSC L62 delivers highly accurate, reproducible results for applications in polymers, metals, ceramics, pharmaceuticals, building materials, and food products.

Applications
Metals & Alloys
Metals and alloys form the backbone of modern industries – from automotive and aerospace engineering to electronics, energy and construction. For reliable use in demanding environments, it is essential to understand their melting and solidification behavior, phase transformations, heat capacity, oxidation stability and crystallization processes, as these parameters directly determine mechanical strength, processing conditions and long-term stability.
The LINSEIS HDSC L62 provides precise and reproducible analysis of these critical thermal properties across a wide temperature range up to 1750 °C. Whether for alloy development, quality assurance or comparison of different material grades, DSC measurements deliver the insights needed to optimize processing parameters, improve product durability and ensure reliable performance in real-world applications.
Application example: Steel (Low-Alloyed Steel)
The specific heat flow rate of a low-alloyed steel sample was measured by HDSC. At 734 °C a change in crystal structure from body-centered to face-centered cubic and a transition in magnetic properties from ferromagnetic to paramagnetic were observed. The melting point was detected at 1411 °C and the liquidus temperature at 1473 °C. All peaks are reversible and appear in the cooling segment as well. The phase transition back to the ferromagnetic state occurs at 637 °C and the crystallization range extends from 1454 °C to 1436 °C.
Application example: DSC DTA powder measurements of ferrites
The components used for production of magnetic ferrites are ZnO, Fe2O3 and Cr2O3. The Chrome oxide is added for modification of magnetic and electric properties. At 735°C the powder forms a mixed ferrite with a spinal structure (exothermal reaction: -20.6 J/g). Above 1034°C and 1321°C the heat flow changes into the endothermic direction due to melting of different phases. The LINSEIS HDSC L62 with type S measuring sensor provides a very stable baseline with an extremely low noise level up to 1600°C. This high sensitivity is essential to perform exact reaction enthalpy measurements and evaluations.
Chemicals
Chemicals are used in a wide variety of applications – from basic raw materials and additives to advanced specialty products in coatings, plastics, electronics and pharmaceuticals. To guarantee consistent quality and safe processing, it is crucial to understand their melting and decomposition behavior, glass transition, crystallinity, oxidation stability and reaction enthalpies, as these thermal properties strongly influence stability, reactivity and long-term performance.
The LINSEIS HDSC L62 enables accurate and reproducible characterization of these key parameters under controlled atmospheres or vacuum conditions up to 1750 °C. Whether for product development, process optimization or safety evaluation, DSC measurements provide valuable insights into reaction kinetics, material compatibility and thermal stability, helping to ensure reliable performance and efficient production in the chemical industry.
Application example: DSC Analysis of Talcum
Talcum (Mg3(OH)2[Si2O5]2) is a mineral that consists of hydrated magnesium silicate. It is used for the production of steatite bodies used as isolators with high resistance and a low dielectric loss factor. Its impurities (chlorite, carbonates) can be determined and detected using DSC. The measurement shows the dehydroxylation of chlorite that appears at 608°C and 848°C as endothermal DSC signals. At 768°C the removal of CO2 can be observed when the contained carbonates decompose into their oxides, releasing the CO2. Finally the dehydroxylation of talc can be seen at 937°C as an endothermal peak as well.
Modulated Cp
Application example: Modulated Cp determination
For highest possible accuracy of Cp, the LINSEIS HDSC allows the usage of modulated heating rate temperature profiles. This method causes a continuous change in heat flow of the sample and the system can monitor the heat uptake much better than with a linear heating profile. The deviation from the literature value is much smaller than with linear DSC runs. The modulated heat flow signal (dark red) leads to a significant better Cp resolution (dark blue) that is only slightly different from the literature (bright blue) over the full temperature range. The bright red curve shows the modulated heating profile.
