Discovery 2500 Differential Scanning Calorimeter (DSC)
Differential Scanning Calorimetry (DSC) measures heat effects associated with phase transitions and chemical reactions as a function of temperature. The DSC 2500 uses temperatures in the range between -150 oC and 400 oC to determine thermal transitions such as glass transitions, crystallization, phase changes, melting, stability, cure kinetics, etc., and related enthalpy in a material under a controlled environment.
Prior to DSC analysis, a sample first needs to be analyzed in our TGA to determine at what temperature the sample loses integrity. That sample can then be run at temperatures lower than this point on the DSC. Samples (around 10 mg) are weighed with our precision scale, then sealed in aluminum crucibles and loaded into an auto-analyzer tray in the DSC 2500.
The DSC has optimal performance of a single sensor giving a very flat baseline that does not need correcting. This technology measures cell resistance, capacitance, delivering an accurate heat flow measurement.
