Abstract
With respect to some embodiments, described herein is an apparatus for the growth and detection of particles suspended in a gas stream, using a working condensation fluid that has a Lewis number greater or less than unity. The apparatus can include a saturation chamber and a condensation chamber and can produce particle growth by way of a system which offers bidirectional temperature control of both chambers. The apparatus can include a detection system of particles in a detection chamber. A test fluid carrying the particles can pass through the detection chamber and be separated from the detection system with a barrier fluid that is also passing through the detection chamber.
