The Aerodynamic Particle Sizer® 3321 (APS™spectrometer) provides
high-resolution, real-time aerodynamic measurements of particlesfrom
0.5 to 20 microns. These unique particle sizers alsomeasures
light-scattering intensity in the equivalent optical size rangeof 0.37
to 20 microns. By providing paired data for each particle, theAPS
spectrometer opens up exciting new possibilities for thoseinterested in
studying the makeup of an aerosol.
