Two-stage hierarchical clustering for analysis and classification of mineral sunscreen and naturally occurring nanoparticles in river water using single-particle ICP-TOFMS
Summary
Single-particle ICP time-of-flight mass spectrometry combined with two-stage hierarchical clustering was used to detect and classify titanium- and zinc-containing nanoparticles from mineral sunscreen against natural particle backgrounds in river water. The method successfully distinguished anthropogenic sunscreen nanoparticles from naturally occurring particles without needing prior knowledge of particle composition.
Ti- and Zn-containing nanoparticles from a mineral-based sunscreen are detected and classified against the natural particle background from river water using single-particle ICP-TOFMS and hierarchical clustering analysis.
