Abstract

MONTAJE DE UN DISPOSITIVO PARA EMPLEO EN EL ANALISIS DE GASES ABSORBIDOS EN LIQUIDOS. CONSISTE EN ENFUNDAR LA SUPERFICIE EXTERIOR DE POR LO MENOS LA ABERTURA DE UN TUBO DE MATERIAL PLASTICO, FLEXIBLE, CON UNA ABERTURA EN SU PARED, CON UNA CAPA DE MATERIAL PERMEABLE A LOS GASES Y BIOLOGICAMENTE COMPATIBLE, QUE PUEDE SER SILASTIC. Y RECUBRIR LA SUPERFICIE INTERIOR DE LA FUNDA QUE ESTA ENCIMA DE DICHA ABERTURA CON UNA CAPA DE MATERIAL PERMEABLE A LOS GASES. POLIMERO DE POLICLORURO DE VINILIDENO O POLITRIFLUOROETILENO CRISTALINO, CUYA PERMEABILIDAD ES SIGNIFICATIVAMENTE MENOR QUE LA DE LA CAPA DE FUNDA. SE UTILIZA PARA LA DETERMINACION CONTINUA DE GASES EN SANGRE O CUALQUIER OTRO LIQUIDO.
