Size and elemental composition of nanoparticles using ion mobility spectrometry with inductively coupled plasma mass spectrometry

The work of Efthymios A. Kapellios (Univ. of Crete, PhD Candidate) and Spiros A. Pergantis on developing new analytical methods for determining the size and elemental composition of nanoparticles has been highlighted on the inside cover of the Journal of Analytical Atomic Spectrometry. In this work the combined use of nanoelectrospray ion mobility spectrometry (IMS) with off-line inductively coupled plasma mass spectrometry (ICP-MS) for determining engineered nanoparticles (NPs) in aqueous solution is demonstrated for the first time. The resulting analytical technique exhibits capabilities for determining the size and metal content of NPs and can also be used for determining NP number concentration. The resolving power exhibited by IMS along with the high sensitivity offered by single particle mode ICP-MS are the main features that make this combination attractive for analysing NPs.
