Polymers play in central role in a wide variety of research projects at the University of Ulm, spanning the fields of sustainable energy storage, photonics and biomedicine. The basic analysis of polymers covers not only determing the moleculuar weights and weight distributions of the sample, but also elucidating the thermal properties of the substance.
The Core Facility EMMA is equipped to analyze polymers or polymer mixtures using gel-permeation chromotography (GPC) and materials in general by thermogravimetric analysis (TGA) und differential scanning calorimetry (DSC). Please famillarize yourself with our capabilities below.
