Royal Society of Chemistry - NPL Symposium

Nanoparticle concentration – critical needs and state-of-the-art measurement, 24 April 2018, Burlington House, London


Symposium Format and Topics

Nanoparticles are increasingly used in innovative products manufactured by advanced industries and provide enhanced, unique properties of great commercial and societal value. The measurement of number concentration of particles in colloidal suspension is of major commercial interest as it enables the optimisation of materials specification and deall for psign, and is essential for risk assessment and quality control. It also supports compliance with regulation and underpins any claim to reliability, performance and lifetime in the formulation of products containing particles.

In recent years, there have been substantial advances in the ability to directly measure particle concentration in colloidal suspension. However, no formal evaluation and validation of available techniques have taken place and nanoparticle reference materials that are certified for number concentration do not yet exist.

This one-day Symposium, organised by the Analytical Division East Anglia Region of the Royal Society of Chemistry (RSC) and the National Physical Laboratory (NPL), will bring together academics, measurement experts, instrument manufacturers, nanomaterials producers and industries interested in their use and applications to:

  • Discuss the state-of-the-art of nanoparticle analysis with focus on nanoparticle number concentration.
  • Present new methods to measure absolute nanoparticle concentration with low uncertainty, alongside the capabilities of a range of commercially available instrumentation.
  • Identify needs and potential pathways to address current limitations in methods, reference materials and protocols.
  • Discuss industrial requirements in the framework of product development, regulatory requirements and the development of standards.

The outputs of the Symposium will be used as input to a variety of international efforts related to measurements of nanomaterials, including national standards organisations, VAMAS and ISO Technical Committees on Nanotechnology.

This Symposium will be followed on Wednesday 25 April by an Open Day, at the same location, dedicated to the outcomes of the European project Innanopart – Metrology for Innovative Nanoparticle – of the European Metrology Programme for Research and Innovation (EMPIR). Themes that will be presented and discussed are measurements of nanoparticle concentration, agglomeration and surface chemistry. Attendees are invited to attend this event free of charge. More details can be found below.
