The Aerodynamic Particle Sizer Spectrometer is a high performance instrument providing measurements on aerodynamic diameter of aerosols and relative light scattering intensity. The instrument provides the diameter of particles using time-of-flight technique on 0.5-20 μm particles, measured in an accelerating flow field with a single high speed timing processor. Simultaneously, a light scattering technique is used to detect particles between 0.37 and 20 μm.

The Aerodynamic Particle Sizer Spectrometer can measure from 0.5 to 20 um by aerodynamic sizing and 0.37 to 20 um by optical detection with aid of 52 particle size channels, can detect minimum particle concentration of 0.001 particles/cm3, has over 200000 particles/sec maximum processing rate for aerodynamic sizing, can program sampling time from 1 s to hours per sample.

The output parameters are particle size raw counts from 52 channels, number, diameter, surface, volume and mass particle size calculated with the aid of its software program.
