Abstract

método e dispositivo de citometria de fluxo sem fluidos envolventes a presente invenção refere-se a um método e a um dispositivo que adotam o método da citometria de fluxo, os quais podem ser usados, de preferência, mas sem a isto se restringir, na contagem e classificação de leucócitos. mais especificamente, ela se refere ao campo dos instrumentos de hematologia simplificados com custos operacionais moderados. o método de acordo com a presente invenção é caracterizado por usar uma técnica de medição de impedância para identificar as partículas cuja trajetória incluiu uma área de medição óptica predeterminada a fim de processá-las seletivamente, evitando assim o uso de fluidos envolventes para manter as partículas dentro da referida área de medição.
