What is ISO/TS 19590 - Inorganic nanoparticles in aqueous media via single-particle inductively coupled plasma mass spectrometry about?

ISO/TS 19590 discusses nanotechnologies. ISO/TS 19590 is an international standard that outlines s ize distribution and concentration of inorganic nanoparticles in aqueous media via single particle inductively coupled plasma mass spectrometry ISO/TS 19590 specifies a method for the detection of nanoparticles in aqueous suspensions and characterization of the particle number and particle mass concentration and the number-based size distribution using ICP-MS in a time-resolved mode to determine the mass of individual nanoparticles and ionic concentrations. The method under ISO/TS 19590 applies for the determination of the size of inorganic nanoparticles (e.g., metal and metal oxides like Au, Ag, TiO2, BVO4, etc.), with size ranges of 10 nm to 100 nm (and larger particles up to 1 000 nm to 2 000 nm) in aqueous suspensions. In addition to the particle concentrations, ionic concentrations in the suspension can also be determined. Note 1: The method und...
