Aerodynamic Particle Sizer APS 3321

Measure aerodynamic particle size from 0.5 to 20 micrometers with the only sizer of its kind on the market. While cascade impactors also size particles by their aerodynamic diameter, the Aerodynamic Particle Sizer® (APS™) spectrometer offers high size resolution, one-second sampling, and real-time size distributions. Time-of-flight aerodynamic sizing determines the particle’s behavior while airborne, and is unaffected by index of refraction or Mie scattering.

Product Details

The Aerodynamic Particle Sizer® (APS™) 3321 spectrometer provides high-resolution, real-time aerodynamic measurements of particles from 0.5 to 20 microns. These unique particle sizers also measures light-scattering intensity in the equivalent optical size range of 0.37 to 20 microns. 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, 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.
