In fifteen words or less, explain the significance of this contribution (Novel Aspect).: We've developed new capabilities for ME-SP-ICP-MS.

Abstract Text: The increasing use of nanoparticles in industry and research has led to a large demand for innovative analytical approaches for their characterization and quantification. Microextraction -single particle - inductively coupled plasma - mass spectrometry (ME-ICP-MS) has been recently developed in our laboratory and can be used to directly analyze particles from sample surfaces. We have previously demonstrated that the technique is capable of extracting Au and Fe nanoparticles loaded on a polytetrafluoroethylene (PTFE) surface and delivering them to an ICP-MS. Here we present our progress on expanding the application space of this technique to include isotopic analysis of particles, detection of challenging elements (e.g., F), and use on a variety of surfaces (e.g. silicon wafers, carbon planchettes etc.). This presentation will include addressing the improvements in the extraction design and the coupling of microextraction to various ICP-MS platforms for respective applications.
