Description of TSI 3938

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.

Features and Benefits

  • High resolution nanoparticle sizing with discreet size channels and single particle counting
  • Independent of optical properties of the aerosol
  • Wide size range: from 1 nm to 1,000 nm depending on configuration
  • High resolution data: 128 channels/decade for up to 384 total possible channels
  • Dynamic concentration range up 107 particles/cm3
  • Fast measurements: < 10 second scans
  • Component design for maximum flexibility with a selection of five Condensation Particle Counters (CPCs), four Differential Mobility Analzers (DMAs), and traditional or non-radioactive neutralizer
  • Easy setup with tool-free installation and autodiscovery of components
  • ISO 15900:2020 compliant
  • PC or touch screen control†

† A computer is needed for wide-range scans and operation of the 1nm SMPS

Applications

  • Environmental monitoring and atmospheric research
  • Nucleation and new particle formation studies
  • Combustion and engine exhaust studies
  • Indoor air quality measurements
  • Inhalation toxicology studies
  • Nanomaterial research and synthesis
