Due to the high sensitivity of balances it is possible to investigate the monomoleqular layers under the ultralow pressure from 0.005 to 1mN/m. At the picture you can see the dependence of surface pressure versus surface concentration for the Langmuir layer of C60.

It is possible to have high quality control of process of the deposition of LB-films. That is the diagram of the deposition of the octadecilphenol to the Si substrate.

By the study of the dependence of the surface potential versus the ionic force it is possible to investigate the surface charge of the surfactantes. That is the dependence of surface potential versus surface concentration for the Langmuir layer of C14F29COOH.
