  • Patent number: 9638665
    Abstract: The invention provides a method for obtaining aerosol particle size distributions with a scanning mobility particle sizer (SMPS) device comprising a differential mobility analyzer (DMA); which method comprises the stages: (i) collecting a first data set of particle concentrations vs. size for a size range from a predetermined minimal size Dmin to an intermediate size Dt by varying a voltage applied to a DMA column of an SMPS from Vmin to Vt1 at a first sheath flow rate Qsh1; (ii) changing the sheath flow rate from the first sheath flow rate Qsh1 to a second sheath flow rate Qsh2; (iii) collecting a second data set of particle concentrations vs.

  • Publication number: 20160139013
    Abstract: The invention provides an apparatus set up for diluting aerosols; the apparatus comprising: (i) a dilution chamber (1); (ii) an aerosol inlet (2) on one side of the dilution chamber for admitting an aerosol into the dilution chamber; (iii) an aerosol outlet (3) on the same or another side of the dilution chamber through which diluted aerosol particles can leave the dilution chamber; (iv) a diluent gas inlet (4) for admitting into the chamber a diluent gas; (v) a diluent gas outlet (5) through which diluent gas can leave the dilution chamber; (vi) a gas flow maintenance system (6) that provides circulation of the diluent gas through the dilution chamber; and (vii) means for determining the extent of dilution of the aerosol leaving the aerosol outlet. The invention also provides methods of diluting and counting aerosol particles using the apparatus of the invention.

  • Publication number: 20150000595
    Abstract: The invention provides an apparatus for increasing the size of gas-entrained particles in order to render the gas-entrained particles detectable by a particle detector, the apparatus comprising an evaporation chamber (2) and a condenser (7); the apparatus is configured so that vapour-laden gas from the evaporation chamber can flow into the condenser and condensation of the vaporisable substance onto gas-entrained particles in the condenser takes place to increase the size of the particles so that they are capable of being detected by a particle detector.

  • Patent number: 8109129
    Abstract: A nanoparticle size classifier comprising a variable flow rate system with a single diffusion element 3 placed inside a cell 2 containing inlet 1 and outlets 6 and 7, an aerosol filter 8, flow meter 9, pump 10 and pump controller 11, which enables a plurality of measurements to be obtained by means of passing an aerosol through the diffusion element 3 at various flow rates. Preferably, outlet of the diffusion cell is connected to a particle counter 5 via a three-way valve 6. The diffusion element has a net or screen that permit air through but capture some particles. In a preferred embodiment, the nanoparticle size classifier is connected to a PC 12 (a notebook or a palm-size computer) to acquire and process data.

  • Patent number: 7372020
    Abstract: Ions in a steady flow sample are counted by colliding the ions in a mixing chamber with a numerical excess of uncharged or neutral aerosol particles, suitably glycerol, entrained in air, to transfer respective charges from the ions to charge individual aerosol particles and passing the gases through a separating chamber subjected to an electric field to direct the charged aerosol particles to impinge upon an optical particle counter.
