  • Process for the determination of the concentration of an ionic or ionizable solute in ion exchange chromatography
    Patent number: 5062961
    Abstract: Process for the determination of the concentration of a solute in a solution whose constituents are known.The first step is to determine the concentration of the hydrogen ions with the aid of an implicit equation as a function of the dissociation constant of the constituents of the solution and the unknown concentration of the solute and then the concentration of the constituents of the solution to which a measurement is sensitive. The concentration of the solute is obtained by comparing the theoretical signal function with the experimental signal.Particular application to ion exchange chromatography systems with or without chemical suppression.
