A novel strategy for the detection and quantification of nanoplastics by single particle inductively coupled plasma mass spectrometry (ICP-MS).

Analytical Chemistry, 2020
A method for the detection and quantification of nanoplastics (NPTs) at environmentally relevant concentrations was de-veloped. It is based on conjugating nanoplastics with functionalized metal (Au)-containing nanoparticles (NPs), thus making them ...

Direct method for the quantitative analysis of surface contamination on ultra-low background materials from exposure to dust [PDF]

, 2020
In this work we present a method for the direct determination of contaminant fallout rates on material surfaces from exposure to dust. Naturally occurring radionuclides K-40, Th-232, U-238 and stable Pb were investigated. Until now, background contributions from dust particulate have largely been estimated from fallout models and assumed dust ...
