Abstract (en)
[origin: WO2005085802A1] The invention relates to a method and device for automatically determine physical and colloidal characteristics selected (for example according to the grain size, distribution of the grain sizes, a hindrance function and a structural stability indexes) by detecting the attenuation of waves injected through mono or polydispersed samples exposed to gravitation or centrifugation. Said invention is characterised in that during separation by gravitation or centrifugation at any moment, simultaneously for several samples which are also concentrated and exhibit known and/or unknown physical or colloidal characteristics, the instantaneous characterising an actual separation state transmission IT(t, r) of the waves injected at intensity I0(t, r) and/or instantaneous diffusion IS(t, r) are detected at a high resolution and repeatedly recorded as a function of the position thereof inside a sample for one or several wavelengths on the entire sample length or the selected segment thereof.
