Images used to calculate the pressure dependence of the saturated methane concentration in water as a function of pressure

We have measured the maximum concentration of methane dissolved in water as a function of pressure using a diamond anvil cell. These images show the sample space with regions of methane (darker) and water+methane (lighter). From the relative areas of these regions we estimated the concentration.我们利用金刚石对顶砧（diamond anvil cell）测量了甲烷在水中的最大溶解浓度随压力变化的关系。这些图像展示了样品空间中的甲烷区域（较暗）和水+甲烷区域（较亮）。我们通过这些区域的相对面积估算出了浓度。
