Abstract

Una curva de corrección se prepara graficando concentraciones de 12CO2 y relaciones de concentración 13CO2 / 12CO2 que son determinadas en base a unacurva de calibración y absorbencias de 13CO2 y 12CO2 de muestras gaseosas que tienen la mismare lación de concentración 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 mideespectrométricamente. Una concentración de 12CO2de la muestra de ensayo gaseosa se determina mediante una medición espectrométrica. Se obtiene un valorde corrección de relación de concentración en base a la curva de corrección y la concentración de 12CO2 de la muestra gaseosa de ensayodeter minada de estemodo. Una relación de concentración 13CO2 / 12CO2 se divide por el valor de corrección de relación de concentración obtenido de esta forma para corregirla relación de concentración 13CO2 / 12CO2. De este modo, se puedemejorar la precisión de la medición de las relaciones de concentración de los gasescomponentes.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 13CO2 / 12CO2 concentration ratio 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 the 12CO2 concentration of the test gas sample mined for this mode. A 13CO2 / 12CO2 concentration ratio is divided by the concentration ratio correction value obtained in this way to correct the 13CO2 / 12CO2 concentration ratio. In this way, the precision of the measurement of the concentration ratios of the component gases can be improved.
