Full Description

BS PD ISO/TS 19590:2017 specifies a method for the detection of nanoparticles in aqueous suspensions andcharacterization of the particle number and particle mass concentration and the number-based sizedistribution using ICP-MS in a time-resolved mode to determine the mass of individual nanoparticlesand ionic concentrations.

The method is applicable for the determination of the size of inorganic nanoparticles (e.g. metal andmetal oxides like Au, Ag, TiO2, BVO4, etc.), with size ranges of 10 nm to 100 nm (and larger particles up to1 000 nm to 2 000 nm) in aqueous suspensions. Metal compounds other than oxides (e.g. sulfides, etc.),metal composites or coated particles with a metal core can be determined if the chemical compositionand density are known. Particle number concentrations that can be determined in aqueous suspensionsrange from 106 particles/L to 109 particles/L which corresponds to mass concentrations in the rangeof approximately 1 ng/L to 1 000 ng/L (for 60 nm Au particles). Actual numbers depend on the type ofmass spectrometer used and the type of nanoparticle analysed.

In addition to the particle concentrations, ionic concentrations in the suspension can also be determined.Limits of detection are comparable with standard ICP-MS measurements. Note that nanoparticles withsizes smaller than the particle size detection limit of the spICP-MS method may be quantified as ionic.

The method proposed in this document is not applicable for the detection and characterization oforganic or carbon-based nanoparticles like encapsulates, fullerenes and carbon nanotubes (CNT). Inaddition, it is not applicable for elements other than carbon and that are difficult to determine with ICPMS.Reference [5] gives an overview of elements that can be detected and the minimum particle sizesthat can be determined with spICP-MS.
