Method of potentiometric detection of copper-complexing agents

摘要

A method of directly detecting amino acids, other organic and inorganic copper-complexing agents, and indirectly detecting non copper-complexing species comprising use of a potentiometric flow-through electrode detector suitable for use in high performance liquid chromatography and autoanalyzers. Said detector comprises a copper metal indicator electrode and a suitable reference electrode within a miniature flow through cell and which detector has the property that it provides a voltage response to the particular molecule to be detected thereby.
