23 paź 2020 · Key Points. 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.
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.
16 cze 2021 · Due to several factors (higher mobility of gases; larger isotope effects; interest in shale, tight, and coal gases; etc.), carbon isotopes of natural gases offer an extensive suite of characterization and interpretative options.
20 sty 2022 · Good knowledge on the stable carbon isotopic composition (δ13C) of fossil fuels is critical for the estimation of atmospheric CO2 sources.
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.
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 a...
A portable stable carbon isotope ratio analyzer for carbon dioxide, based on wavelength scanned cavity ringdown spectroscopy, has been used to detect, locate, and characterize an intentional leakage of CO2 from an underground pipeline at the ZERT exptl. facility in Bozeman, Montana.
