AeroTrakTM 9000 Nanoparticle Aerosol Monitor

The AeroTrakTM 9000 nanoparticle aerosol monitor can measure the surface area of particles deposited in the lungs. The instrument first diffuses and charges the particles, and then uses an electrostatic meter to detect the charged aerosols, providing the deposition surface area of the alveoli (A) or bronchioles (TB). The unit is: μm2/cm3。

It does not directly measure the total surface area of suspended particles in the air (such as Fuch surface area), but rather the surface area fraction of these particles deposited in the alveoli (A) or bronchioles (TB).

Research has shown (Oberdorster, 2001) that the surface size of nanoparticles plays a significant role in their toxicity and is highly correlated with particle induced health effects. The potential pathogenic effects are directly related to the surface area of particulate matter (Driscoll 1996; Oberdorster, 2001).
