Abstract: A system for preparing nanoparticles is described. The system can include a reactor for producing a nanoparticle aerosol comprising nanoparticles in a gas. The system also includes a diffusion pump that has a chamber with an inlet and an outlet. The inlet of the chamber is in fluid communication with an outlet of the reactor. The diffusion pump also includes a reservoir in fluid communication with the chamber for supporting a diffusion pump fluid and a heater for vaporizing the diffusion pump fluid in the reservoir to a vapor. In addition, the diffusion pump has a jet assembly in fluid communication with the reservoir having a nozzle for discharging the vaporized diffusion pump fluid into the chamber. The system can further include a vacuum pump in fluid communication with the outlet of the chamber. A method of preparing nanoparticles is also provided.
