Abstract

Elemento de ensayo analítico para la determinación de un analito en un líquido, que posee un soporte inerte, un elemento de detección y un canal capacitado para el transporte capilar de un líquido, que posee un orificio para la alimentación de muestras en un extremo, y un orificio de ventilación en el otro extremo, del canal capacitado para el transporte capilar de un líquido, realizándose que el canal capacitado para el transporte capilar de un líquido está formado por lo menos parcialmente por el soporte y por el elemento de detección y se extiende en la dirección del transporte capilar desde el orificio para la alimentación de muestras por lo menos hasta la arista del elemento de detección que está situada más próxima al orificio de ventilación, caracterizado porque un rebajo se encuentra en un área que forma el canal capacitado para el transporte capilar de un líquido junto a la arista del elemento de ensayo que forma el orificio para la alimentación de muestras, de tal manera que la arista del elemento de ensayo que forma el orificio para la alimentación de muestras esté interrumpida por lo menos parcialmente en un lado y el área opuesta al rebajo sea puesta al descubierto.
