    摘要： A penetration and removal efficiency calibration unit for a volatile particle remover in a solid particle counting system provides an accurate and efficient approach to calibration. The calibration unit includes an aerosol inlet, a flow meter downstream of the aerosol inlet, and a mixer. The flow meter receives the aerosol flow from the aerosol inlet and provides an output flow to the mixer. The mixer receives the output flow from the flow meter and also has a dilution gas inlet. The mixer provides a mixer output flow for reception by the volatile particle remover or particle counter. A first flow controller controls flow into the dilution gas inlet. The calibration unit also includes a bypass inlet. A second flow controller controls flow into the bypass inlet, and a control loop controls the bypass flow such that the aerosol flow tracks a reference value.

    摘要： 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 poly disperse 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.

    摘要： A wide range continuous diluter for diluting gases that contain small particles to allow subsequent measurement of the diluted gases with an instrument is provided. A dilution gas inlet receives a dilution gas, and a sample gas inlet receives a sample gas. A flow meter measures the sample gas flow rate. A mixer receives and mixes the dilution gas and the sample gas at a dilution ratio. An instrument flow outlet provides a well-defined flow into the instrument from the mixture flow. A make-up gas inlet is arranged to provide make-up gas into the mixture flow at a controlled rate. Because the dilution gas flows at a controlled rate and the mixture flows at a controlled rate, changing the flow rate of the make-up gas causes a responsive change in the sample gas flow rate, thereby allowing continuous adjustment and control of the dilution ratio when desired.

    摘要： A real-time particulate matter measuring system includes a hot diluter for receiving and diluting aerosol . An evaporation unit receives the diluted aerosol. A cold diluter receives and dilutes the output flow from the evaporation unit. A condensation particle counter receives the diluted output flow and measures the particle number concentration. An integrated device also receives the diluted output flow. The integrated device measures at least one of particle diameter concentration arid particle surface area. The integrated device also measures mass concentration.
