Description of TSI 3321

The Aerodynamic Particle Sizer® (APS™) 3321 spectrometer provides high resolution, real-time aerodynamic measurements of particles from 0.5 to 20 μm. This unique particle sizer also measures lightscattering intensity in the equivalent optical size range of 0.37 to 20 μm. By providing paired data for each particle, the APS™ spectrometer opens up exciting new possibilities for those interested in studying the makeup of an aerosol.

The APS™ spectrometer uses a patented*, doublecrest optical system for unmatched sizing accuracy. It also includes a redesigned nozzle configuration and improved signal processing. The result is greater small-particle sizing efficiency, improved accuracy of mass-weighted distributions, and virtual elimination of false background counts.

Features and Benefits

  • Double-crest optics produce high-quality measurements
  • Measures aerodynamic particle size from 0.5 to 20 μm
  • Measures light-scattering intensity from 0.37 to 20 μm
  • Real-time aerodynamic sizing
  • No need to wait for cascade impactor measurements
  • High size resolution – 52 size channels
  • Independent of optical properties of the particles and fluid
