Abstract

método de separação de partículas e aparelho. um método de separação de partículas (p) com diferentes velocidades de sedimentação em uma amostra de fluido (30) através de sedimentação centrífuga que compreende envolver a amostra (30) e girar a amostra em torno de um eixo primário (12) fora da amostra a uma primeira velocidade de rotação (o), e em torno de um eixo secundário (22) localizado no centro da amostra em uma segunda velocidade de rotação ( ) para submeter a amostra a um campo centrífugo variável até que cada partícula (p) tenha se assentado em uma posição que depende da velocidade de sedimentação da partícula.
