23 paź 2020 · Carbon isotopes, 14 C and 13 C, in atmospheric CO 2 are changing in response to fossil fuel emissions and other human activities. Future simulations using different SSPs show continued changes in isotopic ratios that depend on fossil fuel emissions and, for 13 C, BECCS.
29 paź 2023 · We resolve analytical issues and present new carbon isotope ratios of CO 2 in single fluid inclusions with an error better than 2.5‰ (all errors are 1σ unless stated otherwise), providing...
15 kwi 2018 · This research provides a fundamental analysis tool for determining gas carbon isotope composition (δ 13 C values) quantitatively by using Micro-Laser Raman spectroscopy. Experiment of results demonstrates that this method has the potential for obtaining δ 13 C values in natural CO 2 gas reservoirs.
19 mar 2021 · Carbon isotopes, Gases, Inorganic carbon compounds, Liquids, Oxides. Abstract. This work examines the stable isotope fractionation of carbon and oxygen in gaseous, supercritical, and liquid carbon dioxide systems at temperatures from −27.1 to +43.5 °C.
1 sty 2004 · This chapter discusses two different methods for measuring carbon and oxygen isotopes in atmospheric CO 2 and a method for measuring carbon isotopes in atmospheric CH 4. The first method for CO 2 uses traditional dual inlet Isotope Ratio Mass Spectrometry (IRMS) with cryogenic extraction on fairly large air samples.
17 lis 2023 · Isotopic measurements provide valuable information about the origin of greenhouse gases — as carbon dioxide levels increase, there is a corresponding shift towards lighter isotopic composition similar to that of fossil fuels.
3 maj 2023 · GC-MS analytical data for 13 C isotope-tracing experiments in CO 2 photoreduction using the following catalysts: conjugated polymers in liquid (a, b) and gas–solid phase (c).
