Plot of the surface tension (γ) and area. Plot of the surface tension (γ) and area. The area is the surface area that the surfactant occupied on the Langmuir-Wilhelmy balance (expressed as a percentage of total) in A: 21% oxygen and B: 100% oxygen. C: Plot of surface area change (δA) between 21% and 100% oxygen. Horizontal lines represent the mean and whiskers denote ± SD. δA is the change in area expressed as a percentage.
