Differential Scanning Calorimetry (DSC) is an important tool for exploring the thermal behavior of substances in fields such as materials science, chemistry, and biology. The core principle is based on the fact that substances absorb or release heat due to physical or chemical changes during heating or cooling. DSC accurately captures these heat changes by measuring the heat flux difference between the sample and the reference material. ​

 

This instrument can accurately measure the phase transition heat, reaction heat, etc. of substances, such as the heat changes of metal materials during crystallization or melting, and can obtain accurate values through DSC. In terms of qualitative analysis, it can identify the thermal transformation process of substances, such as determining the glass transition temperature of polymer materials, providing key data for material performance research. ​

 

In practical applications, DSC has a wide range of uses. In the food industry, it is possible to detect the phase change of moisture in food and evaluate its shelf life; In the field of drug development, being able to study the crystal transformation of drugs to ensure drug quality and stability; Assist in optimizing the processing technology of polymer materials in research. ​

 

With the development of technology, DSC is constantly upgrading. Nowadays, it has achieved functions such as fast scanning and ultra-low temperature measurement. In the future, its combination with other technologies will further expand its application boundaries and play an important role in more fields, bringing new breakthroughs to scientific research and industrial production.
