Radiocarbon (¹⁴C) is an optimal tracer of methane (CH₄) emissions, as ¹⁴C measurements enable distinguishing between fossil methane and biogenic methane. However, these measurements are particularly challenging, mainly due to technical difficulties in the sampling procedure. We made the sample extraction much simpler and time efficient, providing a new technology that can be used by any research group, with the goal of expanding ¹⁴C measurements for an improved understanding of methane sources.
