Abstract

UN METODO Y UN APARATO PARA DETERMINAR LA CONCENTRACION DE UN COMPUESTO ABSORBENTE DE ENERGIA PREDETERMINADO EN UNA MUESTRA DE ALIENTO RESPIRATORIO. SE HACE PASAR ENERGIA INFRARROJA DE TRES LONGITUDES DE ONDA A TRAVES DE LA MUESTRA RECOGIDA. SE ELIGE UNA PRIMERA LONGITUD DE ONDA DE ENERGIA INFRARROJA, POR EJEMPLO DE 3,95 MICRAS, QUE SEA INSENSIBLE A LA ABSORCION, TANTO POR EL COMPUESTO ABSORBENTE DE ENERGIA PREDETERMINADO, TAL COMO EL ETANOL, COMO POR LOS COMPUESTOS ABSORBENTES DE ENERGIA DESCONOCIDOS, TALES COMO LA ACETONA Y EL VAPOR DE AGUA. SE ELIGE LA SEGUNDA LONGITUD DE ONDA DE ENERGIA INFRARROJA, POR EJEMPLO DE 3,48 MICRAS, QUE SEA NOTABLEMENTE ABSORBIDA POR EL ETANOL. SE ELIGE LA TERCERA LONGITUD DE ONDA DE ENERGIA INFRARROJA, POR EJEMPLO DE 3,39 MICRAS, QUE SEA NOTABLEMENTE ABSORBIDA POR LA ACETONA Y EL VAPOR DE AGUA. SE UTILIZAN AMPLIFICADORES FUNCIONALES SENSIBLES A LA PRIMERA, SEGUNDA Y TERCERA LONGITUDES DE ONDA PREDETERMINADAS DE ENERGIA SUSTRAYENDO EL EFECTO DE LA ABSORCION POR LA ACETONA Y EL VAPOR DE AGUA. SE UTILIZAN AMPLIFICADORES FUNCIONALES SENSIBLES A LA PRIMERA, SEGUNDA Y TERCERA LONGITUDES DE ONDA PREDETERMINADAS DE ENERGIA SUSTRAYENDO EL EFECTO DE LA ABSORCION POR LA ACETONA Y EL VAPOR DE AGUA PARA PRODUCIR UNA SEÑAL ELECTRICA DE SALIDA QUE ES PROPORCIONAL A SOLO LA CONCENTRACION DEL ETANOL.-
