Overview
Utilizing liquid nitrogen cooling, the instrument achieves linear temperature reduction by controlling the flow of liquid nitrogen, capable of reaching as low as -160 degrees Celsius. Differential Scanning Calorimetry (DSC) is a classic thermal analysis method that analyzes thermal effects at controlled program temperatures, and it has long been widely applied in various fields such as research and development of materials and chemicals, process optimization, quality inspection and control, and failure analysis. Using the DSC method, we can study phase transitions in inorganic materials, melting and crystallization processes of polymers, polymorphic phenomena in drugs, solid/liquid phase ratios in foods like fats and oils, etc. Complies with national standards GB/T2951.42-2008, GB/T15065-2009, GB/T17391-1998, GB/T19466.6-2009.
