What Is a Differential Scanning Calorimeter?

The differential scanning calorimeter is a larger differential scanning calorimeter (DSC). Differential scanning calorimeter application range: curing reaction temperature and thermal effect of polymer materials, determination of material phase transition temperature and thermal effect, crystallization of polymer materials, measurement of melting temperature and thermal effect, glass transition of polymer materials temperature.

Differential scanning calorimeter ( Differential Scanning Calorimeter ), which measures the relationship between temperature and heat flow related to the internal thermal transition of materials, has a wide range of applications, especially material development, performance testing and quality control. Material properties such as

DSC

Differential scanning calorimetry (DSC), a thermal analysis method. Under a program-controlled temperature, measure the power difference (eg, in the form of heat) input to the sample and reference as a function of temperature. The curve recorded by the differential scanning calorimeter is called a DSC curve. It takes the rate of heat absorption or exotherm of the sample, that is, the heat flow rate dH / dt (units of millijoules per second) as the ordinate, and the temperature T or time t as the horizontal axis. Coordinates can be used to determine a variety of thermodynamic and kinetic parameters, such as specific heat capacity, reaction heat, transition heat, phase diagram, reaction rate, crystallization rate, polymer crystallinity, sample purity, etc. This method has a wide temperature range (-175 ~ 725 ° C), high resolution, and low sample usage. It is suitable for the analysis of inorganic substances, organic compounds and drugs.
