[Research on Quantitative Method for the Determination of Carbon Isotopic Composition of CO2 with Micro-Laser Raman Spectroscopy].

In this study, a series of 12CO2/N2 and 13CO2/N2 binary mixtures with various molar fraction ratios were synthesized. It was found that the Raman peak area ratios were proportional to molar fraction ratios. The linearity of the working curves was very good.
