Nanotechnologies – Characterization of nano-objects using single particle inductively coupled plasma mass spectrometry

This document describes parameters, conditions and other considerations for the reliable detection, characterization and quantification of nano-objects in aqueous suspension by spICP-MS. Particle number concentration, particle mass, particle mass concentration, particle spherical equivalent diameter, and number-based size distribution are considered the main measurands, but the technique also allows for determination of the dissolved element mass fraction in the sample. This document provides general guidelines and procedures related to spICP-MS application, and specifies minimal reporting requirements.
