<p>A particle generating system includes an aerosol generator, an ejector diluter, and an aerosol diluter. The ejector diluter receives the generated aerosol and dilutes the aerosol to an expected raw concentration. The aerosol diluter further dilutes the aerosol to a concentration in the range of 0% to 100% of the expected raw concentration. The aerosol diluter includes a mini cyclone for diluting the aerosol. The particle generating system may be configured to provide variable concentrations of monodisperse or polydisperse aerosols for instrument calibration. The system may provide constant concentrations in the range of 0% to 100% of the raw concentration. The mini cyclone makes the system compact, and the system may be portable.</p> |
