Application of Crown Ethers as Buffer Additives in Capillary Electrophoresis

This paper provides an overview of the applications of crown ethers as buffer additive in capillary electrophoresis. The applications area can be categorized into the separation of inorganic cations; chiral separation and separation of organic compounds include positional isomers. The use of background electrolytes combining cyclodextrins and crown-ethers for both chiral and non-chiral separation is also presented. Applications published up to the year 2009 from each category are summarized.
