Aerodynamic particle sizer TSI – APS 3321

spektrometr-perex.jpg The aerodynamic particle sizer TSI 3321 is a device for accurate measurement of aerodynamic diameter of aerosol particles. It is a compact and portable general purpose apparatus applicable to measurement of aerosol particle size under laboratory and field operating conditions. The aerodynamic diameter measurement is based on a sophisticated 'time-of-flight' technique. It is a size characteristic of a particle that determines the particle motion behaviour when suspended in the air. The sizer measures simultaneously the aerodynamic diameter and the equivalent diameter; the latter based on scattered light intensity.

Specification

  • real-time measurement of the aerodynamic particle diameter ranging from 0.5 µm to 20 µm at high resolution within the entire range
  • simultaneous measurement of scattered light intensity over the equivalent particle size range between 0.4 µm and 20 µm
  • measurable particle concentration range from 0.001 to 10,000 per cm3
  • particle type: atmospheric solid aerosols and non-volatile liquid aerosols
  • resolution of the aerodynamic diameter 0.02 µm and 0.03 µm for particle size of 1.0 µm and 10 µm, respectively
  • maximum measuring frequency greater than 200,000 particles per second
  • programmable sampling period from 1 second to 18 hours per sample
  • Aerosol Instrument Manager Software for measurement and data analysis
  • compatible aerosol dilutor TSI 3302A is available
  • Aerodynamic Particle Sizer can be combined with Scanning Mobility Particle Sizer Spectrometer (available at the department)
