Differential scanning calorimeter is also referred to as DSC. DSC is to make the sample under the control of a certain temperature program (rise/decrease/constant temperature), and observe the change process of the heat flow power difference between the sample end and the reference end with temperature or time. Obtain relevant thermal effect information such as the endothermic, exothermic and specific heat changes of the sample during the temperature program, and calculate the endothermic and exothermic heat (enthalpy) and characteristic temperature (starting point, peak value, ending point…) of the thermal effect.
Differential scanning calorimeter, as a high-precision detection instrument, mainly studies the physical and chemical transition rates and temperatures, as well as the energy and mass changes involved, when substances are heated or cooled. Other fields of application are very wide, such as: medicine, plastics, coating, food, etc., will use it to study melting and crystallization processes, glass transition, phase transition, liquid crystal transition, curing, oxidation stability, reaction temperature and enthalpy, and Determine the specific heat and purity of the material, study the compatibility of each component in the mixture, calculate the crystallinity, reaction kinetic parameters, etc.
What can a differential scanning calorimeter measure?
- Component analysis. It can be used for the identification and research of organic matter, inorganic matter, medicine, polymer, etc.
- Stability determination. It is mainly used for the determination of sample stability and antioxidant properties.
- Research on chemical reactions. Study the reaction between solid matter and gas, measure catalytic performance, study reaction kinetics, measure reaction heat, study phase transition and crystallization process.
- Material quality inspection. It is used for purity determination, solid fat index determination, polymer quality inspection, glass transition and Curie point of substances, service life of materials, etc.
- Determination of mechanical properties of materials. For the determination of impact resistance, viscoelasticity, elastic modulus, loss modulus, etc.
Differential Scanning Calorimeter
Our DSC Advantages:
- Brand new furnace structure, better resolution and resolution and better baseline stability.
- The parameters can be set to multi-stage heating, constant temperature and cooling. The humanized design reflects the intelligent development of the equipment.
- The instrument can adopt two-way control (host control, software control), with fast running speed and convenient operation.
- Imported chips are used, and the acquisition circuit is shielded and anti-interference processing to ensure the accuracy of the test results.
- The sensor adopts hot-melt technology instead of traditional spot welding technology, and the sensitivity is higher.
