Measure the aerodynamic particle size from 0.5 to 20 micrometers with the only device of its kind available on the market.While cascade impactors determine particle size based on their aerodynamic diameter, the Aerodynamic Particle Sizer (APS™) offers high size resolution, sampling within one second, and real-time size distributions. The aerodynamic time-of-flight measurement determines the behavior of particles in the air and is not influenced by the refractive index or Mie scattering.The APS™ is suitable for a wide range of applications—from inhalation toxicology and air monitoring to drug delivery—and is continually used in new and interesting ways.Product DetailsThe APS™ enables high-resolution, real-time aerodynamic measurements of particles between 0.5 and 20 µm. Additionally, these unique particle sizers can detect scattered light intensity in the corresponding optical range between 0.37 and 20 µm. The APS spectrometer provides paired data for each particle, opening up highly interesting new possibilities for studying aerosol structures.The APS spectrometer uses a patented dual-vertex optical system that offers unparalleled sizing accuracy. It also features a newly designed nozzle configuration and improved signal processing. The result is increased efficiency in sizing small particles, improved accuracy in mass-size distributions, and the near-complete elimination of false background counts.ApplicationsInhalation toxicologyPharmacotherapy studiesAtmospheric studiesEnvironmental air monitoringIndoor air quality testingFilter and air purifier testingCharacterization of test aerosolsParticle size determinationFeatures & BenefitsDual-vertex optics for high-quality measurement dataMeasurement of scattered light intensity between 0.37 and 20 µmMeasurement of aerodynamic particle sizes between 0.5 and 20 µmComponentsAerosol Instrument Manager® SoftwareTechnical Specifications / FeaturesHigh-resolution, real-time aerodynamic particle size measurement (0.5–20 µm)Scattered light intensity detection (0.37–20 µm)Patented dual-vertex optical systemImproved nozzle configuration and signal processingHigh efficiency for small particle sizingImproved mass-size distribution accuracyMinimized false background counts
