Abstract

Un espectrofotómetro infrarrojo IR para la determinación de la relación isotópica en una muestra, que comprende: un primer láser IR ajustable para proporcionar un primer haz a una primera longitud de onda; un segundo láser IR ajustable para proporcionar un segundo haz a una segunda longitud de onda diferente de la primera longitud de onda; una primera celda de absorción (20) para contener una muestra de referencia de relación isotópica conocida y dispuesta para recibir ambos primer y segundo haces; una segunda celda de absorción (30) para contener una muestra de relación isotópica desconocida y dispuesta para recibir ambos primer y segundo haces; un primer detector de absorción óptica dispuesto para detectar dicha primera longitud de onda; un segundo detector de absorción óptica dispuesto para detectar dicha segunda longitud de onda; y un entrelazador (40) dispuesto de tal forma que, alternativamente, la radiación IR transmitida a través de la primera o de la segunda celda de absorción (20, 30) se dirige hacia dichos primero y segundo detectores de absorción óptica, de tal forma que conmuten la radiación IR detectada en el primer y segundo detector de absorción óptica, entre cualquiera de: la radiación IR transmitida a través de la primera celda de absorción (20); o la radiación IR transmitida a través de la segunda celda de absorción (30).
