DSC Thermal Micro-Differential Scanning Analysis Instrument
Differential Scanning Calorimetry (DSC) is a technique used to study materialsThermal properties and phase change behaviorimportant thermal analysis technique, its principle is to simultaneously measure the heat flow generated by the sample under test and the reference material under the same temperature program conditions.Heat Flow。
During the analysis process, the instrument uses a precise temperature control system to heat or cool the sample at a set heating or cooling rate. When the sample undergoes phase changes such as glass transition, crystallization, or melting at specific temperatures, it will absorb or release heat, resulting in a difference in thermal flow compared to the reference material.
These heat flow changes will be detected by the instrument and converted intoDSC curve (Heat Flow vs. Temperature)Through the DSC curve, important thermal property information of materials can be obtained, includingglass transition temperature (Tg), crystallization temperature (Tc), melting point (Tm), heat capacity, and reaction kinetics characteristics, etc.
When the sample is measured alone, the thermal properties of the material itself can be directly obtained. If the sample is attached to another substrate (such as a silicon wafer) or exists in a solution, it is necessary to measure it simultaneously.Heat flow change of the reference materialThen, calibration is performed through differential calculations to ensure the accuracy of the analysis results.
