Abstract

Cette invention concerne un système ainsi qu'un procédé de caractérisation d'un échantillon contenant une macromolécule en solution. Une source de lumière illumine l'échantillon, généralement dans la plage des fréquences de l'ultraviolet visible, tandis que plusieurs capteurs, disposés radialement autour de l'échantillon et selon plusieurs angles d'observation, détectent simultanément l'énergie lumineuse émanant dudit échantillon. Un spectre d'intensité est calculé en fonction de la longueur d'onde pour chaque angle d'observation, lequel spectre permet de calculer une caractéristique de la particule, telle que la forme, les modifications de conformation, la composition, ou encore la répartition granulométrique. Les données sur la dispersion et sur l'absorption sont également utilisées afin d'obtenir des informations complémentaires.
