Welcome to Particle Vision, the particle specialists

We are a passionate, versatile team with solid experience in the analysis of fine particles (abrasion particles from tires, brakes, mineral particles, nanoparticles,...) to support you and help you find a solution to your questions.

Whether it is airborne dust, or particles on surfaces or in water bodies emitted by road and rail traffic, or by construction, quarries, gravel pits, industrial activities, or natural processes (sand events, volcanic eruptions, etc.)... we can help you find a quick solution to your environmental and material question.

Let our analysis services inspire you. We are looking forward to your inquiry by phone

Peer-reviewed scientific article on non-exhaust particles (2021): “Automated identification and quantification of tire wear particles (TWP) in airborne dust: SEM/EDX single particle analysis coupled to a machine learning classifier” https://doi.org/10.1016/j.scitotenv.2021.149832

Our latest report commissioned by the Federal Office for the Environment (FOEN, OFEV, BAFU) on the characterization of airborne dust (PM10-2.5, PM2.5-1 and >PM10) was published at the end of 2020. A summary in English can be found on pages 24-31. Download here: Details as PDF

Thats what our customers say:

  • "We greatly appreciated the ability of the Particle Vision team to develop analytical and statistical methods that allowed us to better characterize fine dusts, their components and their origins. These methods will also be very useful in the future for analysing dust resulting from the abrasion of various metallic or mineral materials."

    Richard Ballaman, Head of the Air Quality Section at the Federal Office for the Environment FOEN
  • «The Office for Nature and Environment (ANU) Graubünden has been working successfully with Particle Vision on several projects since 2014. In addition to the chemical and morphological composition of coarse and fine dust, as well as microparticles, the source contributions of dust particles could also be quantitatively determined thanks to the knowledge and technical equipment of Particle Vision. This has made it possible for the ANU Graubünden to verify the implementation of various measures in wood-burning and industrial activities. But also, in the case of dust disturbances the ANU Graubünden has been supported by Particle Vision, and it was possible to determine the sources of the dust pollution and their contributions to the dust. We can unreservedly recommend the cooperation with Particle Vision.»

    Hanspeter Lötscher, ANU Graubünden
  • «Pleasant and very professional collaboration. State-of-the-art expertise, precious advice and passionate scientific discussions.»

    Dr. Adeline Niquille - Head of Section, Air Protection, Canton of Vaud
  • «The Department of Air, Noise and Non-Ionizing Radiation (SABRA) / State of Geneva has called upon Particle Vision's expertise on several occasions to perform analyses on fine particles measured in the canton. These collaborations, which have highlighted Particle Vision's flexibility and professionalism, have enabled SABRA to obtain detailed information on fine particle emission sources and their composition.»

  • «The Volcanology research team lead by Natalia Pardo, Associate Professor of the Department of Geosciences at the Universidad de Los Andes in Colombia, has been working delightfully with Particle Vision since 2017. In Particle Vision, we have found state-of-the-art technology, outstanding professionals with robust and innovating analytical approaches, committed and patient co-supervision and training of undergrad and MSc students, as well as profound and enriching scientific discussions allowing us to keep on the frontiers research of volcanic ash morphochemistry. Our collaborative results have been successfully presented in international meetings (Cities on Volcanoes 2018, AGU2020), and published in Q1 peer-reviewed international journals.»
