Abstract

Optical chamber for aerosol particle fluorescence measurements is designed. With the designed chamber, UV-induced fluorescent spectrum of single particles can be measured. The design includes two-nozzle flow system, with sheath air flow and virtual impactor concentrator integrated into the chamber. The operation of the flow system was verified with computational fluid dynamics (CFD). The chamber is intended to be used with pulsed UV-laser source, and it includes triggering of the laser pulse to hit individual particles.
