Background

The AEROTRAK™ 9000 Nanoparticle Aerosol Monitor indicates the surface area of nanoparticle aerosols that deposit in the lung, corresponding to the ICRP lung deposition curves for the tracheobronchial (TB) and alveolar (A) regions of the human respiratory tract. The AEROTRAK™ 9000 monitor is a portable, battery-operated diffusion charger + electrometer with real-time surface area concentration readout and data logging capability.

What are Nanoparticles?

Nanoparticles are defined as having dimensions from 1 – 100 nm (0.001 - 0.1 µm) by material scientists and aerosol physicists. Particles in this size range are capable of depositing in all areas of the respiratory tract. Nanoparticles are too small to be measured by traditional mass-based methods and recent research has shown that the surface area of nanoparticles is highly correlated to adverse health effects.

The Aerotrak 9000 Nanoparticle Aerosol Monitor

The AEROTRAK™ 9000 Nanoparticle Aerosol Monitor’s easy to use color touch screen displays data and graphs in real time, shows statistics including 8-hour time weighted average (TWA), minimum, maximum and average surface area concentrations. You can also program custom sampling protocols. With convenient data logging and long battery life, the AEROTRAK™ 9000 is ideal for workplace exposure monitoring, extended workplace sampling and research studies.
