P07 - Development of a Miniaturized Combined DSC and TGA Sensor

Abstract

A miniaturized sensor with both, differential scanning calorimetry (DSC) and combined thermogravimetric analysis (TGA) functionality is presented. The ceramic sensor with integrated heater features high heating and cooling rates and enables the analysis of aggressive materials. The working principle based on the mass-dependent frequency change of the chip as a vibrating cantilever is described. The analysis of copper sulfate pentahydrate (CuSO4 • 5 H2O, an often-used reference substance) proves that DSC and TGA measurements can be carried out simultaneously under real conditions.
