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.
- 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
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.
