This article relates generally to chemical analysis of aqueous solutions and more particularly to a titration method and device for determining the concentration of metal ions and the like in a solution. Titration is widely used in chemical laboratories to determine the concentration of acids, bases, metal ions, oxidizing agents, or reducing agents in aqueous solutions. The determinations generally require some skill on the part of the analyst and often take considerable time. In the approach proposed here, the titrant solution and the soluble indicator traditionally used in titrations are replaced by solid phase reagents bound to beads. The beads are packed into cylindrical columns with transparent walls.
