The SurPASS 3 (Anton Paar) is the latest device enabling the analysis of Zeta potential, an important surface property of materials at the solid-liquid interface. The assessment of this state is an important indicator of the true surface charge of a solid in contact with a solution. The SurPASS3 device with its autotiter unit and wide range of measurement cells will facilitate the understanding of particle agglomeration behaviour, allow the analysis of surface conductivity of solid samples and/or facilitate the prediction or simulation of corrosion behaviour of the materials tested. It finds its application in the evaluation of both solid, mantle and fibrous materials.
Another instrument we have added to the CNT laboratories is the state-of-the-art MCR 702e modular rheometer (Anton Paar) for rheological characterization of solid materials and powder samples. The instrument contains two drive motors operating in a wide range of modes (tension, pressure, torsion). It enables dynamic mechanical analysis (DMA) together with a temperature and humidity chamber, thus significantly advancing the possibilities of material characterization designed for the widest group of materials and nanomaterials from ceramic, metallic, polymeric to nanocomposite. In addition, it has a built-in camera system that realistically monitors material behavior during testing.
