Abstract

Una curva de correccion se prepara graficando concentrados de 12CO2 y relaciones de concentracion 13CO2/12CO2 que son determinados en base a una curva de calibracion y absorbencias de 13CO2 y 12CO2 de muestras gaseosas que tienen la misma relacion de concentracion 13CO2/12CO2 pero diferentes concentraciones conocidas de 12CO2; una muestra gaseosa que contiene 13CO2 y 12CO2 como gases componentes se introduce en una celda y se mide espectrométricamente; una concentracion de 12CO2 de la muestra de ensayo gaseoso se determina mediante una medicion espectrométrica; se obtiene un valor de correccion de relacion de concentracion en base a la curva de correccion y la concentracion de 12CO2 de la muestra gaseosa de ensayo determina de este modo; una relacion de concentracion 13CO2/12CO2 se divide por el valor de correccion de relacion de concentracion obtenido de esta forma para corregir la relacion de concentracion 13CO2/12CO2; de este modo, se puede mejorar la precision de la medicion de las relaciones de concentracion de los gases componentes.
