Abstract

Una curva de correccion se prepara graficando concentraciones de 12C02 y relaciones de concentracion 13C02 / 12C02 que son determinadas en base a unacurva de calibracion y absorbencias de 13C02 y 12C02 de muestras de gaseosas que tienen lamism a relacion de concentracion 13C02 / 12C02 pero diferentesconcentraciones conocidas de 12C02. Una muestra gaseosa que contiene 13C02 y 12C02 como gases componentes se introduce en una celda, y se mideespectrométricamente. Una concentracion de12C02 de la muestra de ensayo gaseosa se determina mediante una medicion espectromérica. Se obtiene un valorde correcion y la concentracion de 12C02 de la muestra gaseosa de ensayo determinada de este modo. Una relacion deconcentracion 13C 02 / 12C02 se dividepor el valor de correccion de relacion de concentracion obtenido de esta forma para corregir la relacion de concentracion 13C02 / 12C02.A correction curve is prepared by graphing 12C02 concentrations and 13C02 / 12C02 concentration ratios that are determined based on a 13C02 and 12C02 calibration curve and absorbances of soda samples that have the same 13C02 / 12C02 concentration ratio but different known concentrations of 12C02. A gaseous sample containing 13C02 and 12C02 as component gases is introduced into a cell, and measured spectrometrically. A 12C02 concentration of the gaseous test sample is determined by a spectromeric measurement. A correction value and the concentration of 12C02 are obtained from the test gas sample thus determined. A concentration ratio 13C 02 / 12C02 is divided by the concentration ratio correction value obtained in this way to correct the concentration ratio 13C02 / 12C02.
