Abstract
The interpretation of dynamic differential calorimetry ("DDSC") data is enhanced by parsing the data according to whether it is obtained while the sample is being heated, cooled, or re-heated. Each DDSC scan is split up into three separate components, depending upon whether the sample is undergoing heating, cooling or reheating. Each component can then be analyzed separately to investigate the sample response to temperature change as the sample is being heated, cooled, or re-heated. Each file is deconvoluted separately, using a deconvolution routine that first removes the effect of the phase lag due to the instrument's finite response time.
