Differential Scanning Calorimeter
The DSC-40BE is a conventional thermal analysis instrument based on the heat flux principle. It measures the difference in heat flow per unit time between a sample and a reference material as a function of temperature or time under programmed temperature control. Requiring only milligram-level sample quantities, the instrument determines key thermal analysis parameters, including enthalpy, melting temperature, crystallization temperature, glass transition temperature, specific heat capacity, purity, oxidation induction period, thermal stability, and Arrhenius kinetic constants.
