Differential Scanning Calorimetry (DSC) Analyzer

The Differential Scanning Calorimetry (DSC) Analyzer is a core thermal analysis instrument used to measure how a material’s physical properties change with temperature. It operates by heating or cooling a sample and an inert reference pan at a controlled, identical rate. The instrument monitors the difference in heat flow required to maintain both pans at the exact same temperature. When the sample undergoes a physical transformation—such as melting, crystallization, or a glass transition—it will either absorb heat (endothermic) or release heat (exothermic). The DSC records these energy changes in real time, producing a thermal curve that serves as a unique fingerprint for the material. Primary Uses: • Polymer & Plastic Characterization: To find the glass transition temperature (T_g), melting point (T_m), and percentage of crystallinity. • Pharmaceutical Analysis: To check drug purity, detect different crystalline structures (polymorphs), and test shelf-life stability. • Chemical Reaction Monitoring: To study curing profiles, cross-linking in resins, and thermal decomposition limits.
