Particle size classification and characterization

Our selection of fine particle measurement instruments includes several real-time and gravimetric instruments for the size-segregation of fine particles based on their aerodynamic diameter. With the High Resolution ELPI®+, the particles can be classified into up to 500 size-fractions in real-time. We also provide instruments for determining standardized PM size fractions, such as PM10, PM2.5 and PM1.0. All Dekati® Instruments use a single measurement technology throughout the entire specified particle size range from a few nanometers up to 10 micrometers. Dekati has instrumentation suitable for:

  • Particle size and concentration studies
  • Particle shape and density studies
  • Particle charge state studies
  • Chemical composition, microscopy, or SEM/TEM studies of a size-segregated aerosol

Particle concentration measurement

We provide complete solutions for real-time determination of number, mass, and surface area concentration of particles. Our instruments also also determination of the charge state of particles in different size fractions in real-time. In addition to real-time instrumentation, our comprehensive selection of instrumentation includes several systems to determine gravimetric PM concentration of airborne particles.

  • Particle number concentration
  • Particle surface area concentration
  • Particle mass concentration
  • Net charge of size-classified particles
  • Bipolar charge of size-classified particles

Particle sampling and collection

Dekati has a market-leading selection of aerosol dilution and conditioning instruments from simple pre-cut devices to computer controlled automated dilution systems. Applications for these systems range from cleanroom technology and laboratory use to dilution and conditioning of combustion generated particles from engines and stationary sources. Our dilution and conditioning devices are designed to enable particle measurements from any sample concentration, temperature, and pressure.

  • Dilution systems
  • Pre-separators for removing large particles from the sample
  • Sample dryers for removing humidity from the sample
  • Catalytic strippers for volatile compound removal
  • Sampling nozzles for isokinetic sampling
  • TSP, PM10, and PM2.5 inlets
