Preferred Label : distribution isotherm;
Detailed label : distribution isotherm in chromatography;
IUPAC definition : The equilibrium relation between the concentration of a sample component in the stationary
phase cS, and in the mobile phase cM, expressed as a function cS f.cM. In some versions
of 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.;
Scope note : the relation can be influenced also by concentrations of other sample components.
csand cm are usually expressed per unit volume of the phase; cs may also be expressed
per mass of the dry solid phase or per unit surface area.;
