The TSI 3321 Aerodynamic Particle Sizer Spectrometer provides high-resolution, real-time aerodynamic measurements of particles from 0.5 to 20 μm. This unique particle sizer also measures light-scattering 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 double-crest 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.
