A portable methane sampling system for radiocarbon-based bioportion measurements and environmental CH4 sourcing studies
Radiocarbon measurements can be used to deduce the proportion of renewable to fossil carbon in materials. While these biofraction measurements are performed routinely on solid and liquid substances, measurements of gaseous samples, such as methane, are still scarce. As a pioneering effort, we have d...
