Abstract

Le procédé est destiné à la quantification de la pureté d'échantillons de particules sous-visibles. Un échantillon à analyser est placé dans un microscope électronique pour obtenir une image de microscopie électronique (100) de l'échantillon. L'échantillon contient des objets (114). Les objets (114) qui ont des tailles différentes d'une plage de tailles de particules primaires (120) et de tailles se situant dans la plage de tailles de particules primaires (120) sont améliorés. Les objets (114) sont détect
