Figure 2.
The schematic depicts an experimental setup with two vessels connected through a central clay sample. Vessel 1 on the left is labelled initially filled with gas A above water and is connected by pipes and valves to the clay chamber. Vessel 2 on the right is labelled initially filled with gas B above water and is similarly connected. The central chamber contains a rectangular clay sample with filters on both sides, allowing connection to each vessel. Pipes, valves, and flow direction symbols indicate controlled gas and water movement between the vessels and the clay section.Schematic design of the setup to measure the diffusion of dissolved gases in the laboratory (modified from Jacops et al., 2015)
