The instrument enables high-quality investigations of various materials and compounds. These include, for example, the structural analysis of fibre composites, the analysis of pore structures and distributions in metallic or matrix-bound materials, or the time- and location-dependent crack formation or delamination of adhered structures as a result of mechanical or thermal stress. The geometric structures of materials can be analysed via high resolution imaging data, which can be transferred into simulation models using automatic image data processing methods. Furthermore, damage processes and others can be detected non-destructively and with great accuracy while still in development.

Gekoppeltes Messsystem FFF-MALS-ICP-MS (Field Flow Fractionation - Multi Angle Light Scattering - Inductive Plasma coupled Mass Spectrometry)
Das gekoppelte Messsystem ist in der Lage, Polymere, Nanopartikel und Mikropartikel unterschiedlicher Struktur, Zusammensetzung und Ladung zu trennen und zu charakterisieren. Das System besteht aus einem Modul für die Fraktionierung und einem Modul für die Detektion. Das Fraktionierungsmodul besteht aus den HPLC-Grundkomponenten Pumpe, Degaser und Autosampler, einem asymmetrischen Fluss-Feldflussfraktionierungs-Kanal (AF4-Kanal), der sowohl durch eine GPC/SEC Säule als auch durch einen AF4-Kanal mit elektrischem Feld ersetzt werden kann. Das Detektionsmodul besteht aus einem Multi-Angle-Laser-Scattering Detektor (MALS), einem Dynamic-Light-Scattering Detektor (DLS), einem Brechungsindex-Detektor (RI), einem UV-Detektor und einem induktiv gekoppelten Plasma – Massenspektrometer (ICP-MS). Mit Hilfe des MALS werden Gyrationsradien der Partikel bestimmt, mit deren Hilfe Molmassen von Polymeren berechnen werden können. In Kombination mit dem hydrodynamischen Radius aus der DLS können Informationen über die Konformation des Polymers und dessen Lösungsstruktur gesammelt werden. Das inline-gekoppelte ICP-MS mit seiner niedrigen Nachweisgrenze und schnellen Detektion gibt Hinweise auf die chemische Zusammensetzung der Partikel. Mit der transienten Aufzeichnung vieler Massespuren soll es möglich werden, organische von anorganischen Partikeln zu unterscheiden.
