METHOD AND APPARATUS FOR GENERATING HIGH PURITY ELUANT

摘要

A method and apparatus is provided for generating a high purity eluant suitable for use in chromatography. The high purity eluant may be generated by providing water and a first stationary phase comprising exchangeable cations . Electrolysis ions are generated by the electrolysis of water. The electrolys is ions are selected from the group consisting of hydronium ions and hydroxide ions. The hydronium ions are passed through the first stationary phase so th at the hydronium ions replace the cations in the first stationary phase. Thereafter, a source of desired ions is combined with the cations to form a high purity eluant containing the desired ions.
