  • Device for determining the size distribution of aerosol particles
    Patent number: 7140266
    Abstract: The invention relates to a device (30) for determining the size distribution of aerosol particles from a flow (11), the device (30) comprising an electric mobility analyzer (10) and an impactor (20), connected to each other in such a way that the nozzle part (22a) of the first stage of the impactor (20) is simultaneously the bottom plate of said mobility analyzer (10).
    Type: Grant
    Filed: August 31, 2001
    Date of Patent: November 28, 2006
    Assignee: Dekati Oy
    Inventors: Marko Marjamaki, Mikko Moisio, Jorma Keskinen, Juha Tikkanen
  • Method of measuring density properties of a particle distribution
    Patent number: 7131343
    Abstract: A method and a device for measuring density properies of a particle distribution, in which method a first parameter relating to the particle distribution is measured at a first measuring point (302), at least part of the flow that passed through the first measuring point is guided to the second measuring point (304), a second parameter relating to the particle distribution is measured at a second measuring point (305), and said first and second parameters relating to the particle distribution are used to determine at least one density property of the particle distribution of the original flow (306).

  • Method for measuring properties of a particle distribution
    Patent number: 7066037
    Abstract: A method and a device for measuring properties of a particle distribution, in which a parameter relating to the mobility of the particles is measured at one measuring point (302) and a parameter relating to the aerodynamic size of the particles is measured at a second measuring point (305). By means of the measured parameters, at least one property of the particle distribution of the original flow is determined (306).
