Differential Scanning Calorimetry
Overview:
Differential Scanning Calorimetry measures the heat input required to raise the temperature of a material. Similar to TGA, it provides a curve of energy input (heat flux) vs. temperature or temperature vs. time. Based off of a reference sample, a constant input of energy is used to increase the temperature, typically with a calibration cycle beforehand to remove any processing effects (although this can be bypassed). This technique is typically used for polymers, and is especially useful in material characterization of composites due to differing melting temperatures within composite components.
