The present disclosure describes an apparatus for detecting particles in a gas by saturating the gas with vapor and causing the gas to flow through a chamber with walls that are at a temperature different than the temperature of the entering gas creating a gas turbulence within the chamber resulting in the gas becoming super-saturated with vapor and causing said super-saturated vapor to condense on said particles and form droplets, which are then detected and counted by an optical light-scattering detector.
An apparatus for saturating a gas containing particles with vapor for said vapor to condense on said particles to form droplets for detection, said apparatus including a chamber for being partially filled with a liquid to form a liquid surface in said chamber, said chamber including an inlet for said gas to enter and fill the space above said liquid surface, and a plurality of porous panels partially immersed in said liquid to accept liquid in the porous panels, thereby permitting said liquid to evaporate from said wetted porous panels for forming vapor in said gas above the liquid surfaces, said chamber including an outlet for said gas carrying said vapor to exit said chamber.
