How it works
A Condensation Particle Counter (CPC) uses the same laser scatter method of detection as many of our other dust monitors. A Condensation Particle Counter is however able to measure much smaller nanoparticles than a normal laser-based dust monitor due to the condensation chamber. In the condensation chamber, dust particles are exposed to a supersaturated solution of n-Butanol. The butanol condenses on the surface of the dust particles, causing them to grow to a sufficient size for laser scatter detection.
