Abstract
El método es para la cuantificación de la pureza de muestras de partículas sub-visibles. Una muestra que será analizada es colocada en un microscopio electrónico con el fin de obtener una imagen de microscopia electrónica (100) de la muestra. La muestra contiene objetos (114). Los objetos (114) que tengan tamaños diferentes al intervalo de tamaño de las partículas primarias (120) y tamaños que están dentro del intervalo de tamaño de las partículas primarias (120) son mejorados. Los objetos (114) son detectados como siendo partículas primarias (120) o restos (106). Las partículas primarias detectadas (120) son excluidas de los objetos (114) de una manera tal que los objetos (114) contienen restos (106) pero no partículas primarias (120). Es medida una primera área total (T1) de los restos detectados (106). Es medida una segunda área total (T2) de las partículas primarias detectadas (120).
