DSC PT 1600
High temperature Differential Scanning Calorimeter (HDSC) up to 1750°C
Description
On point
Differential Scanning Calorimetry (DSC) stands as the most widely used thermal analysis technique due to its ability to provide a wealth of valuable information. LINSEIS has introduced the high-temperature DSC PT 1600 (HDSC/DTA), meticulously designed to offer exceptional calorimetric sensitivity, minimal time constants, and a sample chamber that remains free from condensation.
These outstanding features ensure not only superior resolution but also baseline stability throughout the entire lifespan of the instrument. As a result, the HDSC/DTA becomes an indispensable tool for material development, research and development (R&D) efforts, and quality control processes.
What sets the HDSC/DTA system apart is its modular concept, which allows for the use of different furnaces encompassing an impressive temperature range from -150°C to a remarkable 1750°C, making it an incredibly versatile and adaptable instrument.
Thanks to its vacuum-tight design, this system facilitates the precise determination of quantitative enthalpy and specific heat (Cp) under the purest of atmospheres and even under a vacuum as low as 10E-5mbar. For enhanced functionality, the systems can be upgraded with an optional sample robot and seamlessly integrated with Mass Spectrometry (MS) or Fourier-Transform Infrared Spectroscopy (FTIR).
Measuring System:
Our measuring system offers user-friendly, interchangeable components, including a DTA Sensor and two distinct DSC Sensors. For the DSC PT 1600, each DSC Sensor is available in types E, K, S, and B. This versatility allows for the ideal selection to suit any application, temperature range, or atmospheric condition.

Applications
Applications example: Ferrite’s production
The components employed in the production of magnetic ferrites include ZnO, Fe2O3, and Cr2O3. The addition of Cr2O3 serves to modify the magnetic and electrical properties of the ferrite. At 735°C, these powders combine to create a mixed ferrite structure, marked by an exothermic reaction releasing -20.6 J/g of energy.
Beyond the temperature range of 1034°C to 1321°C, the heat flow exhibits a pronounced shift in the endothermic direction due to the melting of various phases. The Linseis DSC PT 1600, equipped with the type S-measuring head, maintains a remarkably stable baseline with an exceptionally low noise level, ensuring reliable performance up to 1450°C. This high sensitivity is crucial for achieving precise enthalpy measurements and evaluations.
