Abstract: A method and a device for the automatic determination of selected physical and colloidal chemistry parameters by determining the attenuation of radiated waves through monodisperse or polydisperse dispersion samples subjected to gravitation or centrifugation, wherein during the segregation by means of centrifugation or gravitation, the instantaneous transmission IT(t, r) characterizing the current segregation status of the waves radiated with the intensity Io(t, r) and/or the instantaneous scattering IS(t, r) as a function of the position within the samples is repeatedly determined and recorded at high resolution at any arbitrary time for one or more wavelengths over the entire length of the sample or in selected partial sections of it, simultaneously for multiple and even concentrated samples with known and/or unknown physical and colloidal chemistry properties.

Abstract: The invention relates to methods and devices for accelerated stability analysis, and in particular to a qualitative and quantitative direct estimation/identification of separation processes of disperse material systems (such as liquid-solid, liquid-liquid or liquid-gaseous). The invention also relates to methods and devices for the classification and quantitative characterization of slow, as well as rapid separation phenomena of disperse material systems of different volume concentration. Exemplary fields of application concern the development, selection and optimization of destabilizers, stabilizers and novel formulations for dispersions, as well as quality and process control (such as in the chemical, pharmaceutical, biotechnological, cosmetic and food industries), as well as in the process technology for separation and treatment processes.
