High temperature condensation particle counter

Kanchit Rongchai (Energy)

 

Adverse health effects and measurement of aerosol nanoparticles have increasing concerned scientific and policy making communities. CPCs measure number concentration of nanoparticles by condensing a fluid on their surface to enlarge to optically detectable sizes. Prevailing CPCs operate at around ambient temperature meaning hot engine exhaust needs to be cooled before measurement which may effect the morphology of the particles. In order to avoid cooling, it would be useful to design a high temperature CPC.
