Precise characterisation of aerosols – finely distributed particles in gas – is becoming increasingly important in industry and the environment. Particle measurement devices are increasingly used in the approval and monitoring of clean rooms, as well as for the assessment of particle emissions and immissions in the environment and in production facilities.
In the particle and aerosol laboratory, we ensure traceability to internationally agreed reference values with our high-precision measurement devices and measurement procedures. With our services we support the administration, industry and research in their quest for reliable and accurate measurement.
In order to keep up with the pace of development, we are constantly refining our measurement facilities. With this aim in mind, we conduct various research and development projects. Our speciality is the generation and determination of the size and number concentration of a wide range of solid and liquid particles in aerosols.
With our services we cover a particle concentration range from 100 cm-3 to 107 cm-3 for particle sizes from 5 nm to 5 μm.
With our calibration services, we ensure that particle measurement devices meet national standards. Our analysis and calibration certificates are internationally recognised.
Approvals and conformity assessments
We carry out national type approvals of measurement instruments for diesel smoke. Please contact METAS Cert for conformity assessments of nanoparticle measurement instruments for internal combustion engines.
We calibrate nanoparticle measurement instruments for internal combustion engines.
If you have any questions concerning our services or need advice, we will be pleased to help. Contact us without obligation.

R & D
With the aid of research and development projects, we keep our measurement facilities and expertise at the forefront of technology. We thus ensure our ability to offer the required services and promote innovation in the years to come. In the course of this, we work with other metrology institutes, universities, the administration and industry.
As a research partner of Innosuisse (Swiss Innovation Agency) we cooperate in Innosuisse projects. We are interested in a collaboration with industry. Our strengths lie in the generation of traceable analyses of synthetic and natural aerosols.
