Atelier du CCQM "Particle Metrology"

25 au 27 octobre 2022

Particle WS

Register to the plenary sessions (25 and 27 October)


Register to the breakout sessions (26 October)



The CCQM Workshop on Particle Metrology will be held from 25th to 27th October as an online-only meeting. Free registration is now open using the online registration links above. The meeting will consist of plenary sessions on 25th and 27th October and parallel breakout sessions on the 26th October. Separate registration is required for the plenary sessions and for the breakout sessions. An outline of the current programme is available in the “Working Documents” section below. The full workshop agenda with invited speakers will be provided shortly.

Particles are everywhere, occurring in the environment naturally and as products of human activity, or engineered for science and technology applications that are important to our modern world. Anthropogenic particles found in nature are often damaging to ecosystems and human health. An excellent example is air-suspended particulates in the sub-micrometre size range, which are responsible for many premature deaths worldwide each year, as well as micrometre particles, which cause adverse health effects.

But particles are also very important to modern science and technology, with useful applications in every industrial sector. As examples, carbon nanotubes are added to rubber to improve automotive tire performance, nanoparticles have been added to food and cosmetics to improve their properties, nanoparticles can be added to steel to make it stronger, and nanoparticles are being utilized for drugs that have higher efficacy and reduced side effects compared to more conventional drugs. Given the broad effects and applications of particles, and the need for their accurate measurement in all the locations they occur, the topic is inherently of great interest to the CCQM and its working groups.

Key topics

The workshop will include dedicated sessions on the metrology of:

  • particles suspended in air or other gases
  • particles suspended in water or other liquids
  • particles in biological materials and pharmaceuticals


The objectives of this workshop are:

  • To foster a meaningful information exchange between the CCQM working groups and their stakeholders on the current state of particle metrology, with emphasis on gaps pertinent to modern science and technology.
  • To inform the CCQM working groups regarding currently overlooked activities that need to be undertaken, and to develop a CCQM action plan based on the workshop findings.
