The joint research project "KoDeKa-Plast" between the European Center for Dispersion Technology (EZD) in Selb and the Institute for Laser Technologies in Medicine and Metrology (ILM) at the University of Ulm has been successfully completed. The researchers not only succeeded in efficiently detecting microparticles in water, but also in identifying plastic particles and even gaining insights into the release of microparticles. At the same time, the measurement effort was significantly reduced compared to conventional methods.
