Verfahren zur Bestimmung der mittleren Teilchengroesse und kontinuierlichen UEberwachung der Korngroessenverteilung in polydispersen Suspensionen hoher Konzentrationen |
摘要 |
A method for measuring the diameter of particles in a suspension wherein a particle-free layer having substantially the same refractive index as the suspending medium is provided directly above the suspension and the upper surface of the suspension is illuminated at a large angle of incidence by a beam of radiation passing through the particle-free layer and the intensity of radiation that is scattered by the suspended particles and then re-enters the layer is measured for one or more small scattering angles. These measurements of scattered radiation provide a measure of the mean particle diameter of the suspended particles that is substantially independent of the concentration of particles in the suspension. |
