Single-particle inductively coupled plasma–mass spectrometry (spICP-MS) is becoming widely used to measure the number of nanoparticles (or other submicrometer– sized particles) per mL with a particular elemental chemical composition and the average particle size (diameter) or particle size distribution.

In celebration of Spectroscopy’s 35th Anniversary, leading experts discuss important issues and challenges in analytical spectroscopy.
