We’re looking at nanoplastics in drinking water

SOLVE is part of a project that will investigate micro- and nanoplastics in drinking water. By using our AF4 in combination with Heart-Cutting HC-GC/MS (pyrolysis GC-MS), nanoparticles will be fractionated for characterization, quantification and plastic type determination. We will also study if pipe relining is contributing to plastic particles in the water we drink. The…
