The equilibrium relation between the concentration of a sample component in the , and in the , expressed as a function . In some versions of
stationary phase
mobile phase
chromatography
, a distribution isotherm can be seen as a partition isotherm
, an adsorption isotherm
, or a combination of these, depending on the mechanism of separation.Note:
The relation can be influenced also by concentrations of other sample components. and are usually expressed per unit volume of the phase; may also be expressed per mass of the dry solid phase or per unit surface area.
The relation can be influenced also by concentrations of other sample components.
This definition supersedes an earlier definition of distribution isotherm.
