Advanced water condensation technology with laminar flow for ultrafine particles

摘要

This technology involves the enlargement of air particles with diameters on the order of a few nanometers to hundreds of nanometers by water condensation in a laminar flow to form droplets of diameters on the order of several microns. The technology presents several advanced designs, including the use of two-stage capacitors. It finds application in the measurement of the number concentration of particles suspended in air or other gas, in the collection of these particles or in the focussing of these particles.
