Spectroscopy Solutions has developed an on-demand version of its 'Applications and New Developments in ICP-MS and Related Techniques eSeminar'. This online educational event will provide those using these techniques updates and guidance on the latest methods, protocols, processes and developments with key experts providing practical insights into their respective fields.
In this presentation James F. Ranville from the Department of Chemistry & Geochemistry, Colorado School of Mines, USA will demonstrate how combining single particle ICP-MS with FFF provides a detailed characterization of complex nanomaterials and nanoparticle mixtures and how these methods can provide insight into the transformations and fate of nanoparticles introduced into the environment.
Given the continued growth of the nanotechnology industry and the prevalence of nanotechnology-enabled products, release of engineered nanomaterials (ENMs) into the environment during the material lifecycle is inevitable. A 2014 report by Lux Research shows that, worldwide, the revenue from NEPs grew from $339 billion in 2010 to more than $1 trillion in 2013, and global funding for emerging nanotechnologies has increased by 40-45% per year over that same time period.
The development of new nano-metrology to quantify (mass, particle number concentration) and characterize (size, composition, structure, aggregation state) ENMs is essential to assessing the impacts of their release. This need is recognized by the Nanomaterial Measurement Infrastructure (NMI) core research area of the NNI, which aims to “establish a comprehensive set of measurement tools— instruments, protocols and assays, standards, benchmark data, and models—to enable accurate and reproducible measurements of ENMs and NEPs”. The work presented herein aims to address this necessity.
By viewing this presentation you will understand how:
- combining spICP-MS with FFF provides a detailed characterization of complex nanomaterials and nanoparticle mixtures
- combined with dissolution methods they can reveal structure
- the methods can provide insight into the transformations and fate of nanoparticles introduced into the environment
