Abstract
A particle measuring system and method is capable of separating particles on a size-by-size basis and measuring the number and size of the particles one by one on a real time basis. The particle measuring system includes a sampling device for guiding a stream of an aerosol containing particles suspended in a gas, an analysis device for separating one by one the particles contained in the aerosol, a filter for filtering out the particles contained in the aerosol to produce a filtered gas, a saturating device for saturating the filtered gas with working liquid to thereby produce a saturated gas, a condensing device for condensing the saturated gas to produce liquid droplets each having a nucleus formed of one of the particles, and an optical particle counter for calculating the number and size of the particles contained in the liquid droplets.
