Overview
Utilizing liquid nitrogen cooling, the instrument achieves linear temperature reduction by controlling the flow of liquid nitrogen, with the lowest temperature reaching minus 150 degrees Celsius. Differential Scanning Calorimetry (DSC) is a classic thermal analysis method for studying the thermal effects under controlled program temperatures, and it has been widely applied in various fields such as research and development, process optimization, quality inspection and control, and failure analysis of materials and chemicals today. Using the DSC method, we can study phase transitions of inorganic materials, melting and crystallization processes of polymer materials, polymorphism of drugs, solid/liquid phase ratios of food oils, etc. Compliant with national standards GB/T2951.42-2008, GB/T15065-2009, GB/T17391-1998, and GB/T19466.6-2009.
