DSC with the TGA/SDTA851e Taking Weight Loss into Account

The SDTA signal of TGA/SDTA851e module can be converted into a DSC heat flow curve using an ajustment curve, which can be determined with a good degree of accuracy for the entire temperature range and then saved. The obtained DSC curve can be normalized not only with respect to the initial sample weight but also to the changing weight of the sample. This article describes the procedures to achieve this using the Mathematics option in the evaluation software, several examples are presented.
