partial isotherm (individual isotherm)

in surface chemistry
The function relating, at constant temperature and pressure, the amount of a particular component in the @I03085@ per unit area (or per unit mass of @A00153@ ) with its @A00296@ (or concentration) in the liquid phase. This function can be evaluated only when the location and the thickness of the @I03085@ have been defined.
