Instrument : Condensation Particle Counter (CPC)

Instrument Categories
Aerosols

A Condensation Particle Counter measures sub-micron aerosol particle number concentration by growing the particles to a size that is easily detectable and countable by optical scattering. The condensating liquid is typically an alcohol (e.g., butanol) or water. Depending on the CPC model, the commercial CPC instruments can cover a size range from 3 nm to 3000 nm (ultrafine) or 10 nm to 3000 nm (fine).

The CPC is part of the Aerosol Observing System (AOS).
