Product Details

Nanoparticles are subject to losses by diffusion. This effect can be used to selectively exclude certain size fractions from measurement devices. This size selector was designed to be used with instruments such as Condensation Particle Counters (CPCs) to measure differences between defined particle size ranges. CPCs detect nanoparticles efficiently down to 1 nm depending on the model. By attaching a particle size selector to the CPC inlet, the lower counting efficiency (D50%) can be moved to larger particle sizes, depending on the instrument’s inlet flow and the number of diffusion screens used in the size selector.

The table below highlights a few of the possibilities:

Inlet Flow (L/min) 0.3 0.6 0.7 1.0 1.5
Number of Diffusion Screens Particle Size Cut (D50%) (nm)
1 32 26 24 17 14
4 102 80 75 52 42
9 216 164 145 102 81


Features and benefits

  • Selectively removes small particles from an aerosol by diffusion
