Abstract

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.
