Printable version

The Zefon Personal Nanoparticle Respiratory Deposition (NRD) sampler is designed to size-selectively collect nanoparticles with an efficiency that matches their deposition in the respiratory tract system.


Features
  • Designed to collect particles that mimic those collected in the respiratory tract (<300nm).
  • Lightweight, easily worn by a worker
  • Chemical analysis allows the exposure assessment of nanoparticle of a specific composition apart from other airborne particles.
  • Uses a personal sampling pump.
  • Disposable – ready to use. Sampler does not require preloading or cleaning (cyclones used with the sampler are reused and cleaned, the NRD sampler itself is disposable).
  • Cost effective lab analysis (vs electron microscopy)

How it works:
Stage 1 – A respirable aluminum cyclone (Zefon #ZA0075) at a flow rate of 2.5 LPM is used to remove particles larger than 4µm in size.


Stage 2 – Air passes through an impaction stage where particles larger than 300nm are removed using an impaction plate.


Stage 3 – Air passes through a diffusion stage consisting of a series of Nylon filters, collecting particles <300nm with an efficiency designed to match the efficiency at which particles deposit in the respiratory tract.



Note: Aluminum cyclone sold separately.
