This month we have a HOT article from our Associate Editor for the Americas, John W. Olesik and Patrick J. Gray, from Ohio State University, USA. Nanoparticles and microparticles are used in so many products nowadays, but the rapid, simultaneous characterization of their elemental chemical composition is very tricky. In the following paper, the unique considerations to determine the number of particles per liter and analyte mass (particle size) distributions from single particle ICP-MS measurements using quadrupole or sequential sector field mass spectrometry is explored.
Considerations for measurement of individual nanoparticles or microparticles by ICP-MS: determination of the number of particles and the analyte mass in each particle
