Abstract: Disclosed are a method and a device for determining characteristics of particles dispersed in gases and liquids in the nano- and microscale size ranges and the number distribution and concentration thereof by use of particle photometry. This can be achieved by producing scattered light measurements in a photometer for a different number of aperture or receiving angles and evaluating particle characteristics from the determined scattered light intensities using evaluation algorithms. The determination of particle characteristics over a size range of several decades is made possible without the need to change or adapt the geometry of the sample measurement chamber.

Abstract: Modeling the gravitational field-induced or centrifugal field-induced separation of particles of a dispersion by use of one or more additional force fields that also influence the migration of the particles. A method includes detecting and measuring the modified separation behavior with the help of concentration-measuring sensors. The force acting upon the particles can be calculated from the change in velocity of the particles, and the corresponding particle properties can be calculated if the respective field intensities are known.
