Abstract

método de quantificação da pureza de amostra de partículas subvisíveis. a amostra a ser analisada é colocada em um microscópio eletrônico para se obter uma imagem de miscroscopia eletrônica (100) da amostra. a amostra contém objetos (114). os objetos (114) que apresentam tamanhos diferentes aos da faixa de tamanhos de partículas primárias (120) e tamanhos que estão dentro da faixa de tamanho de partículas primárias (120) são aprimorados. os objetos (114) são detectados como sendo partículas primárias (120) ou resíduos (106). as partículas primárias detectadas (120) são excluídas dos objetos restantes (114) para que os objetos (114) contenham somente resíduos (106) e nenhuma partícula primária (120). uma primeira área total (t1) dos resíduos detectados (106) é medida. uma segunda área total (t2) das partículas primárias detectadas (120) é medida.
