Patent ID: 8370081

Claim:
A method for characterization and determination of particle properties by an impact of superimposed fields, comprising: modeling gravitational field-induced and/or centrifugal field-induced separation of particles of a dispersion using one or more additional force fields that also influence migration of the particles; characterizing a separation behavior of the particles using concentration-measuring sensors, the behavior being modified as a function of magnitude and direction of forces operating in addition, with the characterizing performed across an entire sample length by concentration profiles resolved in time and space; and determining alteration of particle concentration as a quantity for particle properties upon which an additional force acts, and/or determining changes of velocity vectors of the particles from concentration profiles resolved in time and space which have occurred as a function of the magnitude and direction of the forces acting in addition, from which a particle property upon which the additional force acts, is determined qualitatively and/or quantitatively.
