Condensation particle counter
Appearance
A condensation particle counter or CPC is a particle counter that detects and counts small particles by first enlarging them by using the particles to create droplets in a supersaturated gas. [1]
Three techniques have been used to produce nulceation:
- Adiabatic expansion using an expansion chamber. This was the original technique used by John Aitken in 1888. [2]
- Thermal diffusion.
- Mixing of hot and cold gases. [1]
