The invention relates to a device () for determining the size distribution of aerosol particles from a flow (), the device () comprising an electric mobility analyzer () and an impactor (), connected to each other in such a way that the nozzle part () of the first stage of the impactor () is simultaneously the bottom plate of said mobility analyzer ().

Device for determining the size distribution of aerosol particles

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 (), at least part of the flow that passed through the first measuring point is guided to the second measuring point (), a second parameter relating to the particle distribution is measured at a second measuring point (), 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 ().

Method of measuring density properties of a particle distribution

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 () and a parameter relating to the aerodynamic size of the particles is measured at a second measuring point (). By means of the measured parameters, at least one property of the particle distribution of the original flow is determined ().
