Abstract

DISPOSITIVO DE TEXT CROMATOGRAFICO PARA DETECCION DE LA PRESENCIA DE UNA SUSTANCIA EN UN LIQUIDO SIMPLE Y QUE INCORPORA COMO MINIMO DOS ZONAS EN QUE EL FLUIDO CONDUCE (3,4) LAS CUALES FORMAS CAMINOS DE FLUJO DE LIQUIDOS SEPARADOS DE FORMA QUE MANAN HACIA LA REGION (8) EN EL DISPOSITIVO DURANTE EL TEXT, EN DONDE EL CONTROL DE LOS FLUJOS DEL LIQUIDO RELATIVOS A LOS CAMINOS DE FLUJOS SEPARADOS SE CONSIGUEN CON FACILIDAD; COMO MINIMO EN PARTE, ASEGURANDO QUE UNOS DE LOS CAMINOS DE FLUJO SE INTENSIFIQUE O SE RESTRINJA DURANTE EL CURSO DE LA PRUEBA. TAL CONTROL SE CONSIGUE POR LA INCORPORACION DE UN MATERIAL INFABLE LIQUIDO 11 QUE SE ACOPLA PARA INFLARSE POR EL CONTACTO CON EL LIQUIDO SIMPLE Y/O REACTIVO Y PARA HACER ROMPER EL CONTACTO ENTRE LAS DOS ZONAS QUE CONDUCEN EL LIQUIDO.
