The TSI Scanning Mobility Particle Sizer™ (SMPS™) spectrometer is the standard for measuring the size distribution of nanoparticles in air. The method is described in the ISO standard 15900:2020 and hundreds of scientific publications from national metrology institutions and other leading academic and industrial researchers. The results are independent of the refractive index of the solid or liquid aerosol, and have a high degree of absolute sizing accuracy and measurement repeatability. TSI’s model 3938 is the 3rd generation of SMPS; trusted by researchers for over 30 years.
