CCC / CAIS-ECAC: The 2nd ACTRIS intercomparison and calibration workshop for nano particle size spectrometers (nano-MPSS, optimized <10nm) held in Helsinki in May 2026

The 2nd ACTRIS intercomparison and calibration workshop for nano particle size spectrometers (nano-MPSS, optimized <10nm) was organized in Helsinki in May 2026. These workshops are the activity of the Cluster Calibration Center, which is a unit under the ACTRIS Center for Aerosol In-Situ Measurements hosted by University of Helsinki. The aim of the unit is to standardize the measurements of sub-10 nm aerosol particles and develop their calibration methods and practices. The workshop included participants from one ACTRIS National Facility, two external companies and recently developed UF-DMPS by the University of Helsinki/ CCC.
