Abstract

Una curva de correccion se prepara graficando concentraciones de 12CO2 y relaciones de concentracion 13CO2 / 12CO2 que son determinadas en base a unacurva de calibracion y absorbencias de 13CO2 y 12CO2 de muestras gaseosas que tienen la misma relacion de concentracion 13CO2 / 12CO2 pero diferentesconcentraciones 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 dela muestra de ensayo gaseosa se determina mediante una medicion espectrométrica. Se obtiene un valorde correccion de relacion de concentracion en base a la curva de correccion y la concentracion de 12CO2 de la muestra gaseosa de ensayo determinada de estemodo. Una relacion de concentracion 13CO2 / 12CO2 se divide por el valor de correccion de relacion de concentracion obtenido de esta forma para corregirla relacion de concentracion 13CO2 / 12CO2.A correction curve is prepared by graphing 12CO2 concentrations and 13CO2 / 12CO2 concentration ratios that are determined based on a calibration curve and absorbances of 13CO2 and 12CO2 from gaseous samples that have the same ratio of 13CO2 / 12CO2 concentration but different known concentrations of 12CO2 . A gaseous sample containing 13CO2 and 12CO2 as component gases is introduced into a cell, and measured spectrometrically. A 12CO2 concentration of the gaseous test sample is determined by a spectrometric measurement. A concentration ratio correction value is obtained based on the correction curve and 12CO2 concentration of the test gas sample determined in this way. A concentration ratio 13CO2 / 12CO2 is divided by the concentration ratio correction value obtained in this way to correct the concentration ratio 13CO2 / 12CO2.
