Abstract

METODO Y DISPOSITIVO PARA DETERMINAR LA CONCENTRACION DE UNO O MAS GASES, POR EJEMPLO, O{SUB,2} O CO{SUB,2} O UN GAS ANESTESICO, EN UN FLUIDO, POR EJEMPLO, UN FLUIDO CORPORAL O UNA MEZCLA DE GAS. UNA MEMBRANA (12) PERMEABLE A LOS GASES RETIENE UN SOLVENTE (22), POR EJEMPLO, DIMETILSULFOXIDO. EN CONTACTO CON EL SOLVENTE, SE ENCUENTRA UN ELECTRODO ACTUANTE (24) DEL AREA DE SUPERFICIE PREFERIBLEMENTE MENOR A 10 {MI} CUADRADAS. EL POTENCIAL DEL ELECTRODO ACTUANTE ES BARRIDO SOBRE UN INTERVALO PARA REDUCIR CADA UNO DE LOS GASES Y A UN INDICE PARA MINIMIZAR LAS INTERREACCIONES ENTRE LOS GASES Y SUS PRODUCTOS DE REDUCCION.
