Patent number: 4953389Abstract: A method and an apparatus for determining the surface tension between a gas and a liquid, and wherein the surface tension of a film established on the surface of a bubble in a medium may be calculated. A liquid medium such as an aqueous medium is provided in a chamber. The container is constructed so that an air bubble may be formed in the liquid medium in the chamber and a film of a material, such as a surfactant material, can then be formed at the air-liquid interface. The chamber is also constructed so that the pressure of the liquid medium may be varied. On increasing the pressure of the liquid medium, the bubble volume and its surface area are reduced. Thus, the interfacial film is compressed, and alternatively, when the pressure of the liquid medium is reduced, the film is expanded by the expanding of the bubble. The chamber provides a complete enclosure so that the liquid medium and the surfactant are not exposed to the atmosphere.Type: GrantFiled: October 17, 1989Date of Patent: September 4, 1990Assignee: University of CalgaryInventor: Samuel Schurch
