The EAF4 system was used to measure the electrophoretic mobility and zeta potential of 50 nm Ag nanoparticles (AgNPs) coated with three different coating materials.

Plastic micro- and nanoparticles are increasingly in the headlines, particularly when discussing marine pollution, but also with regard to their potential impact on human health. In this application note, we present data on separation of polystyrene nanoplastics, and demonstrate how electrical asymmetrical flow field-flow fractionation (EAF4) can be used for simultaneous size separation and particle surface charge measurement.

In this study, AF4-MALS-ICP-MS was applied to characterize four commercial tattoo inks: outlining black, purple deep violet, green grasshopper, and blue ice.
