Static multiple light scattering to monitor protein aggregation and pigments dispersibility

 
A technique based on Static Multiple Light Scattering is proposed to measure mean particles size in a large range of concentration between 0.0001 and 95%, for sizes between 10 nm and 100 Ám by Turbiscan LAB technology. This technique has the advantage to measure in one click, without sample preparation or dilution, the mean particles size and so the dispersibility efficiency particularly for concentrated suspensions. Other optical techniques such as DLS or PTA can perform this measurement but only at a very high dilution which denatures the agglomerates and give an erroneous size of the native particles. In this work we present different studies : mean size measurement of various products, dispersibility characterization of pigments, protein aggregation monitoring.
