Liquid Surfaces
YKI's instrument park is divided into a number of categories. The Liquid surfaces category includes
Surface Tension
Foams and Thin Films
Adsorption at the Liquid Surface
Surface Tension
The origin of the surface tension is the fact that the molecules close to the surface are statistically further apart compared to the molecules in the bulk. Measuring the surface tension of solutions allows the determination of adsorption of components.

Foams and Thin Films
Foams are normally characterized by determination of the foam number and the foam average lifetime. The lifetime of a foam can be characterized by the Ross-Miles method or by the Bikerman method.

Adsorption at the Liquid Surface
Molecules with a lower surface energy tend to accumulate at the liquid/air surface. The state of the molecule can only be determined through spectroscopy.
