Bestimmung des Enantiomerenüberschusses von chiralen Ammonium‐Ionen mit Hilfe von Flüssigmembranelektroden

Abstract
Determination of the Enantiomeric Excess of Chiral Ammonium long Using Liquid Membrane ElectrodesA cell assembly with two membranes each containing one enantiomer of a chiral ionophore is described. It is suitable for the direct potentiometric determination of the enantiomeric excess of ions. The method is used to determine the enantiomeric excess of ephedronium ions in aqueous solutions.
