New Nanoparticle Exposure Monitor

TSI (UK) recently introduced a new nanoparticle exposure monitor, the AEROTRAK™ 9000 Nanoparticle Aerosol Monitor.The AEROTRAK 9000 is an industrial hygiene tool for measuring a new metric for nanoparticle aerosol exposure – lung deposited surface area. Surface area is the measurement metric that research has shown to be highly correlated with exposure and dosing of nanoparticle aerosols. The AEROTRAK™ 9000 monitor is a portable, battery-operated diffusion charger + electrometer with real-time surface area concentration readout and data logging capability. Nanoparticles are defined as having dimensions from 1 – 100 nm (0.001 - 0.1 ìm) 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’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 AEROTRAKâ„¢ 9000 is ideal for workplace exposure monitoring, extended workplace sampling and research studies.
