Application of Amino Acids as Eluents in Ion Chromatography

Abstract
The possibility of utilization of monoaminocarboxylic acids as eluents in ion chromatography with suppression has been studied. Ion chromatographic behavior of valine, leucine, lisine, glicine, α-alanine, β-alanine and n-aminobenzoic acid has been investigated. Salts of acids are weak eluents, whereas salts of aminobenzoic acid are eluents of middle strength. The application of these eluents wakes it possible to increase the sensitivity of determination, in comparison with the use of mixture Na2CO3/NaHCO3, and to obtain accurate separation of mixtures of F-, Cl-, NO3-, SO42- and HPO42-.
