Abstract

Dispositivos de ensayo. Un dispositivo de ensayo que incorpora una tira de material compuesto que consta de al menos dos cuerpos de un material poroso conductor de flujo que juntos definen parte de una trayectoria de flujo de líquido a través de la cual debe fluir un líquido durante la realización de un análisis, en el que la dimensión lateral de la zona de contacto del cuerpo situado corriente arriba se estrecha de tal manera que el flujo de líquido desde el cuerpo situado corriente arriba al cuerpo situado corriente abajo es Concentrado hacia la línea central de la trayectoria de flujo en el cuerpo situado corriente abajo, reduciendo de esta manera la probabilidad de que el líquido se desvíe de la trayectoria de flujo prevista. El cuerpo situado corriente arriba puede ser una mecha de recogida de muestra.
