Interpreting DSC curvesPart 1: Dynamic measurementsThe art of interpreting curves has yet to be integrated into commercially available com-puter programs. The interpretation of a DSC measurement curve is therefore still some-thing you have to do yourself. It requires a considerable amount of experience in thermalanalysis as well as a knowledge of the possible reactions that your particular sample article presents tips and information that should help you with the systematic inter-pretation of DSC artifactsThe first thing to do is to examine the curve for any obvious artifacts that could lead to apossible misinterpretation of the results.
Fig. 2. Above: Artifact due to a PE film that was not pressed down firmly in the pan (dotted line). The sample of film that was pressed down on the base of the pan with the lid of a light Al pan gave the "correct" melting curve. Below: DSC heating curve of 1.92 mg polystyrene showing a typical artifact at about 78 °C caused by
