Electrochemical Langmuir Trough
Read full article onlineFull Article
The term electrochemical Langmuir trough is used to describe a modification of the original Langmuir trough in which compression isotherms and thus surface areas per molecule can be measured at the interface between two conducting liquids at a controlled electrical potential. The instrument has been used to investigate molecular surface areas as a function of applied potential and to examine insoluble monolayers on mercury surface. These include films built from trigonal connectors and believed to have an open grid structure.
