MODEL 5561


Sampling from 0.8 to 1,100nm

The GRIMM 5561 electrostatic precipitator is a sampler for aerosols over a wide size range from 0.8 – 1100 nm. The particles can be collected for off-line analysis on different substrates that are suitable for a variety of common analytical tools like transmission electron microscopes (TEM), scanning electron microscopes (SEM) or atomic force microscopes (AFM). For sampling well defined size fractions, all GRIMM DMAs are designed to be combined with the precipitator.


  • particle collection on different substrates
  • collection of size-selected particles
  • compatible with all GRIMM DMAs
  • user-selectable voltage and electrode diameters


  • investigation of particle morphology by TEM, SEM or AFM
  • composition of single particles or of bulk samples
