In conventional DSC, Cp is generally calculated (equation [2]) from the difference in heat flow between a blank (empty pan) run and a sample run under identical conditions. Curves 1 and 2 in Figure 4 show typical curves for sapphire. Cp = KCp x Heat Flow (Sample) - Heat Flow (Blank) Heating Rate [2]

WebDifferential scanning calorimetry (DSC) is a method of measuring the flow of heat into or out of a material with respect to time or temperature. Polymer crystallinity can be measured with DSC by quantifying the heat associated with melting (fusion) of the polymer. The heat can be evaluated in terms of % crystallinity by ratioing against a ... WebDifferential scanning calorimetry (DSC) is a very powerful tool for the study of starches given its high sensitivity and ease of use. For the successful characterization of starches, it is important to have a high performance DSC instrument, as the critical transitions associated with starches are very weak and can be difficult to detect. ...
