"What you cannot sample, you cannot detect it also!"

Assets and limits of different biological aerosol sampling technologies

  • parameters having impact on the biological aerosol sampling quality:
    • particle speed during collection
    • dissication
    • crushing of particle on surface 
    • particule bouncing
    • amount of sampled volume
    • l'évaporation
    • retention rate
    • sampling time 
    • indoor sampling 
    • outdoor sampling
    • ration beetween retention rate and sampled volume
    • aerodynamic size of collected particles
  • types of samplers 
    • impactors
    • impingers or liquid impactors
    • les virtual impactors
    • cyclones
      • dry 
      • humid
  • Why are humid cyclones representing the best alternative technology available for collecting enough volume with the best particle retention rates
    • How to test humid cyclones for their performance:
  1. Legionella detection in aerosols 
  2. Aspergillus spp detection in aerosols
  3. Particle counting and bacteria cells counts
  4. Are plate count the best methods to evaluate viable microorganisms in aerosols?
