Isocratic liquid chromatography polymers

THEORETICAL ASPECTS OF ISOCRATIC LIQUID CHROMATOGRAPHY OF POLYMERS... [Pg.94]

A characteristic of small-molecule liquid chromatography is the reversibility of their contacts with the stationary phase. The distribution equilibrium constant determines the duration of the stationary periods and, thus, the retention of the solute. With polymers, isocratic retention factors of normal degree (i.e., 1 gk 10) generally do not occur. A fractional alteration of elution conditions may cause transition from zero retention to infinity. As a rule of thumb, polymers either pass without retention or remain in the column. This off or on behavior produces the impression of irreversible fixation under the conditions of retention. [Pg.162]
