The DSC 214 Polyma: Ideal for Temperature-Modulated Measurements
17 Jul 2014
Modulated DSC measurements are used to separate overlapping effects. The sample is subjected not only to linear heating rate, but also to sinusoidal temperature variations. This method leads to separation of the so-called reversing and non-reversing part of the heat flow. The reversing effects are a function of temperature and oscillate with temperature variations. The non-reversing processes are a function of time and are calculated as the difference between the total heat flow and the reversing heat flow.
