Condensation Particle Counter

In general, laminar-flow CPCs operate by drawing an aerosol sample continuously through a heated saturator, in which alcohol is vaporised and diffuses into the sample stream. Together, the aerosol sample and alcohol vapour pass into a cooled condenser where the alcohol vapour becomes supersaturated and ready to con dense. Particles present in the sample stream serve as condensation sites for the alcohol vapour. Once condensation begins, particles grow quickly into larger alcohol drop lets and pass through an optical detector where they are counted easily.
