Abstract

Correct curves (Fig. 19) were prepared with the 12CO2 concentration point and the 13CO2 / 12CO2 concentration ratio, which were determined on the standard of the calibration and suction curves 13CO2 and 12CO2 of the sample gas. With the same 13CO2 / 12CO2 concentration ratio but a known different 12CO2 ratio The gas samples with 13CO2 and 12CO2 are gases. The elements are introduced into the cell, and spectrometric are measured. The 12CO2 concentration of the test sample as gases is determined by the method of specification measurements. The chromated value makes the correct concentration ratio obtained on the curve standard. And the 12CO2 concentration of the sample in the test probe was gas was obtained. The measured concentration ratios of 13CO2 / 12CO2 were divided by the correct value of the obtained concentration ratios for making the 13CO2 / 12CO2 concentration ratios correct. Element gas can be improved
