Method and device for the characterization of multiple samples of one or various dispersions
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.
