differential scanning calorimetry(dsc)

it is to measure the heat flux differential changes  between sample and reference under the process of temperature variation(up/down/constant temperature).

by differential scanning calorimeter, we can study on materials’ melting and crystallization process, degree of crystallinity , glass transition, phase transformation, liquid crystalline transition, oxidation stability(oxidation induction time(oit)), reaction temperature and reaction enthalpy, measure materials’ specific heat and purity,  study on the compatibility of polymer blend, the curing process of thermosetting resin, and make reaction kinetics study, etc. this method can be widely applied to the industries of plastic, rubber, fiber, coating, adhesive, medicine, food, biological organism , inorganic material, metal material, composite, etc.
