Ion Chromatography: An Account of Its Conception and Early Development

Abstract
Today, ion chromatography means any chromatographic technique that may be applied to the determination of ions or of species that may be converted to ionic form. In its early days however, IC focused on the determination of simple inorganic ions. At one time, the determination of many common inorganic ions was a slow and tedious matter requiring many different, specialized methods that frequently lacked the sensitivity that the problems demanded. In the late 1950s, a small group of chemists at the Dow Chemical Company envisioned replacing these classical methods of inorganic analysis with but a single, universal chromatographic technique. They called their project "Inorganic Chromatography". This article describes how they developed this concept into a new technique, ready for commercial development into what we know today as "Ion Chromatography". In particular, the account will describe: how the Dow scientists adapted electrical conductance monitoring to chromatography, the introduction of the suppressor to chromatography, the invention of special stationary phases, and the evolution of strategies and principles that would shape and guide the practice of ion chromatography for many years to come.
