Basis for innovative PFAS filter made of clay

06.12.2023

PFAS filters available for industrial waste are usually made of activated carbon (PFAS = perfluorinated and polyfluorinated alkyl compounds). As this is comparatively expensive, researchers are looking for alternative filter materials for the so-called "eternal toxins", whose hazardous residues only degrade very slowly in the environment.

Autonomous measuring instruments systematically detect new materials

31.10.2023

Despite highly specialized methods that can simultaneously produce a range of materials on a single sample and then measure them automatically, every minute counts when analyzing them: because days or even weeks can pass before the characterization of a sample is complete. The new algorithm can be integrated into existing measuring instruments to boost their efficiency significantly.

PFAS ban: "Most of the PFAS substances used industrially do not pose a risk to humans or the environment"

31.10.2023

The intended European Union ban on per- and polyfluoroalkyl substances (PFAS) is causing discussion throughout Europe. Many companies in the medical technology sector fear that they will no longer be able to reliably manufacture products as before. We talked to expert Dr. Martin Leonhard, who chairs the medical technology section of the German industry association SPECTARIS.
