Quantitative measurement of carbon isotopic composition in CO gas reservoir by Micro-Laser Raman spectroscopy.

The use of Micro-Laser Raman spectroscopy technology for quantitatively determining gas carbon isotope composition is presented. In this study, CO and CO were mixed with N at various molar fraction ratios to obtain Raman quantification factors (F and F), which provide a theoretical basis for calculating the δC value. And the corresponding values were 0.

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.
