Introduction. The processes of sediment suspensions and sols in gravitational and in centrifugal field and the combined action of the electric field on the particle and the field of gravity, and also their advantages and disadvantages are discussed in this work. Materials and performance. The time of sedimentation particles different radius is calculated on the way to an inch as it moves under the influence of gravity, centrifugal and electric fields as the example of the colloidal particles quartz SiO2. Resume. The effectiveness of the methods deposition colloidal particles under the influence of different fields is assessed. The conclusion concerning the alternatives to sedimentation analysis under the influence of the centrifugal field sedimentation analysis using an electric field is given.
